• ✅ Dropdown hints via slash‑separated options, e.g., {{c1::Paris::London/Paris/Berlin/Madrid}}
• ✅ Non‑destructive and compatible with existing cloze notes and templates
• ✅ Works with Anki 2.1.x

🚀 Quick Start

• Install from AnkiWeb: https://ankiweb.net/shared/info/917616596
• Add‑on code: 917616596 (Anki → Tools → Add‑ons → Get Add‑ons… → paste the code → OK → restart)
• In your cloze card template, replace:
  • {{cloze:YourField}} → {{type:cloze:YourField}}
  • Add the filter: {{type:cloze:YourField|fill-blanks}}
• Create cloze deletions as usual: {{c1::answer}}

🍅 Pomodoro Task - Task-Integrated Pomodoro for Obsidian

An Obsidian plugin that embeds the Pomodoro Technique into your Markdown tasks. Start timers from tagged tasks, log completed cycles directly in the task line, manage subtasks, and navigate documents with markers—all without leaving your notes.

🎯 Features

• ✅ Task-focused timer: start sessions from tasks tagged with a configurable tag (default: #pomodoro)
• ✅ Automatic progress logging: appends tomato counters in-line (e.g., 🍅:: 3 or 🍅:: 2/5)
• ✅ Goal-aware completion: auto-checks the task when the goal is reached
• ✅ Flexible controls: pause, resume, reset, switch work/break, adjust durations on the fly
• ✅ Subtask management: view and toggle subtasks from the timer view, with limits and filters
• ✅ Document markers: add anchors and navigate via a floating widget
• ✅ Sound notifications: configurable sounds for start/complete/pause with volume control
• ✅ Statistics: track total cycles and cumulative focus time with manual reset
• ✅ Highly configurable: work/short/long break durations, start paused, subtask visibility, filters
• ✅ Compatibility: Obsidian v0.15+ on Windows, macOS, Linux, iOS, and Android; works alongside Tasks and Dataview

🚀 Quick Start

• Install via Obsidian → Settings → Community Plugins → Browse → search “Pomodoro Task” → Install → Enable
• Open the panel: click the alarm clock icon in the ribbon or run the command “Pomodoro Task: Open View”
• Create a task with the target tag, for example:
  • • Write project documentation #pomodoro
• Start a session by clicking a listed task; the timer begins immediately
• When a work session ends, the task line is updated with a tomato counter:
  • • 🍅:: 1 Write project documentation #pomodoro
• Optional goals: set a target (e.g., 4) and the task will show progress as 🍅:: 2/4 and auto-complete at the goal

📧 Email Workflow Manager - Email workflows in Thunderbird

A Thunderbird extension to organize related emails into events with custom types and statuses. Track progress, add reminders, and see everything in a clear Type → Status → Event view.

🎯 Features

• Organize emails into Events with fully customizable Types and Statuses
• One Event can belong to multiple Types, each with its own Status
• Email associations persist even when messages are moved between folders
• Tree view with search and filters for quick navigation
• Drag and drop Events between Statuses to update progress
• Thunderbird integration: colored tags and WFM columns in the message list
• Built-in Agenda for deadlines, reminders, and overdue indicators
• Simple backup and restore; export/import your data anytime
• Personalize names, colors, order, and visibility of Statuses
• Main panel and sidebar for quick access

Requires Thunderbird 115 or later.

🚀 Getting Started

• Install via Thunderbird → Add-ons and Themes → search “Email Workflow Manager” → Install → Enable
• Create your Workflow Types (e.g., Support, Warranty, Priority)
• Add Statuses with names and colors for each Type
• Create your first Event (e.g., “Shirt Return - John Smith”)
• Link emails to the Event via the email’s context menu or message view
• Track progress by moving the Event across Statuses
• Add schedules (deadlines/follow-ups/meetings) and monitor them in the Agenda

🧭 Typical Workflow

• Receive emails about a specific topic
• Create an Event and associate all related emails
• Set Status per Type (e.g., “In Review” under Support; “Valid” under Warranty)
• Use drag and drop to update Status as work progresses
• Add deadlines and reminders; review and complete them in the Agenda
• See the Event state directly in the message list via colored tags and WFM columns

🔎 Quick Tips

• Enable WFM columns in the message list header to view Type, Status, and Event
• Use the panel search to find Events by name or description
• Sync tags if you change colors/statuses and want emails to reflect updates
• Export your data periodically to keep a current backup

🧠 Anki Media Fix — Media Recovery for Obsidian-to-Anki Workflows

An Obsidian plugin designed to restore missing images and audio files in Anki flashcards generated through Markdown-based synchronization pipelines.

It integrates with flashcard export ecosystems that rely on AnkiConnect communication.

🔗 Supported Sync Pipelines

Compatible with major Obsidian-to-Anki workflows:

• Obsidian to Anki — Export-based synchronization
• Flashcards (Alex Colucci) — Native flashcard integration
• Anki Sync — Direct card generation and sync
• Yanki — Pure Markdown syntax cards
• AnkiBridge — Strict grammar bridge
• Any integration using AnkiConnect API

⚠️ Problem Addressed — Missing Media in Anki

During synchronization workflows, Anki may lose references to media files used by flashcards, resulting in:

• Broken image placeholders
• Missing audio playback
• Empty content blocks in cards

This typically occurs when media files are not present in Anki’s collection folder but still exist inside the Obsidian vault.

The plugin resolves this by locating the original media inside the vault and re-injecting it into Anki’s media database through AnkiConnect.

🎯 Features

• ✅ Detect missing images and audio used by cards
• ✅ Recover media directly from the Obsidian vault
• ✅ Send only missing files (fast incremental repair)
• ✅ Optional full re-sync of all media
• ✅ Preview missing files before repair
• ✅ Compatible with any plugin using AnkiConnect
• ✅ Non-destructive — does not modify notes or decks

💹 Opção Real — Online Option Pricing (Web, .NET)

An online .NET web application for calculating the fair value of financial options using stochastic modeling and robust numerical methods. It estimates the best option price through classical quantitative finance techniques such as Newton–Raphson calibration and binomial tree valuation.

This software was developed and presented as a Final Undergraduate Thesis (TCC) for obtaining the Bachelor’s degree in Computer Science.

🎯 Features

• ✅ Stochastic Option Pricing — valuation based on stochastic processes and probabilistic modeling
• ✅ Black–Scholes Closed-Form Pricing — computes option prices through the classical analytical Black–Scholes model
• ✅ Fair Value Estimation — computes the valor justo of an option under configurable assumptions
• ✅ Newton–Raphson Method — iterative numerical solver for calibration and implied parameter estimation
• ✅ Binomial Tree Model (Árvore Binomial) — lattice-based pricing for European and American-style options
• ✅ Online Web Interface — run pricing simulations directly in the browser
• ✅ .NET Web Stack — built with Microsoft .NET for scalable online financial computation

🚀 Typical Use Cases

• Pricing call/put options with fair value methodology
• Comparing lattice-based vs. stochastic approaches
• Parameter calibration and sensitivity exploration
• Educational and analytical experimentation with option models

🧬 Note Type Export — Backup and Transfer of Anki Note Types

An Anki add-on that lets you export and import note types (card models) as .json files.

It allows you to save, share, or restore your card structure — fields, templates, and styling — without exporting the entire deck.

🤔 What is this for?

In Anki, a note type defines:

• Fields (Front, Back, Extra, etc.)
• Card template
• Visual style (CSS)
• How cards are generated

Normally this information stays locked inside Anki’s database.
This plugin turns it into a portable file.

So you can:

• Move your models to another computer
• Share your study system
• Backup your templates
• Recover after collection corruption

🎯 What the plugin does

• Exports note types to a .json file
• Imports note types into any collection
• Automatically handles conflicts
• Lets you choose exactly which models to transfer
• Does not modify existing cards
