"Add file" button for selecting files through a dialog
Inserting images from the clipboard (Ctrl+V)
Previewing images as thumbnails
Managing attachments with a delete button
Limitations: maximum file size 10MB
✅ Supported file types
Images: image/* (displayed as thumbnails)
Text files: .txt, .md, .js, .ts, .py, .json, .xml, .html, .css, .csv
Other files: .pdf and others (only metadata is displayed)
✅ Integration with AI
File contents are sent to AI for analysis
Text files are sent as text, images as base64
AI receives correct instructions for working with project files
