- Backend: - Implemented robust Veo video generation including 'lastFrame' and 'referenceImages' support - Fixed video URI extraction with recursive search for API response stability - Implemented direct HTTP video download to resolve SDK method missing errors - Frontend (Video Generator): - Updated validation to allow Text-to-Video for Veo without requiring a first frame - Fixed job state clearing to prevent UI from showing previous completion status - Frontend (My Files & Library): - Moved batch actions toolbar to bottom-left to prevent blocking pagination - Added 'Deselect All' button to batch actions toolbar - Added file type indicators to asset cards - Components: - Added 'Clear Finished' button to Active Jobs tracker - Updated Asset Library modal toolbar positioning
