Btodo is a simple addon for writing down and manage notes, todos and texts into blender built-in text editor. It provides a simple UI integrated into text-editor’s properties panel to create, rename and tag text data-block. It allows to add custom notes as comments to every single object, too. 

Perfect for:

• writing down your ideas;
• planning your work;
• writing todo-lists;
• easily managing teamwork;
• not forgetting anything with object’s notes;
• not losing your ideas. Everything is packed into the project's .blend file;

Main panel: categories

Main features:

• create/remove categories;
• create/remove notes for each category;
• add custom notes and comments to every object into the scene;
• add existing text’s datablock as a new note
• create/remove new tags and assign/remove them to/from notes;
• move notes between categories;
• list notes by category or by tag;
• check-list usage with a ‘check’ parameter for todo-like notes;
• rename categories, notes and tags (do not change text’s datablock name directly from blender UI, instead use buttons on the side of the lists!!);
• rearrange items to match your preferences.

Categorize, tag, add, write, organize, complete, delete.

Control each panel's visibility.

Three tabs:

• category view: add/remove categories and filter notes by category
• tag's view: add/remove tags and sort filter by tag
• object view: list all notes added to the active object

These tabs are also 'unpacked' in the scene and object properties to better fit your workflow. Show/hide panels based on your preferences.

Be careful:

• when you delete an object, you lose all notes attached to it;
• when you delete a category also you lose all its notes;
• when you delete a tag from tag’s list also it removes it from every note.
