BLENDER - Post-it 3D

# 3D Post-it Notes

A Blender addon that allows placing sticky notes directly on 3D models surfaces. Notes can be freely positioned on any surface, are visible in the viewport but never in renders, and provide a modern intuitive interface for collaborative 3D workflows.

## Features

- **Interactive Surface Placement**: Click directly on any 3D surface to place notes with automatic normal alignment

- **Multiple Note Types**: Comment, Issue, Suggestion, and Question - each with distinct icons and default colors

- **Note Management**: Create, edit, move, archive, and delete notes with ease

- **User System**: Track note authors with customizable user colors

- **Smart Visibility**: Notes are visible in viewport but automatically hidden in renders

- **Persistent Storage**: All notes are saved automatically and persist between Blender sessions

- **Surface Alignment**: Notes automatically orient themselves to match surface normals

- **Filtering System**: Filter notes by type, status, or show/hide archived notes

- **Bulk Operations**: Delete all notes or delete by type with confirmation dialogs
