## Bug fixes & improvements

Another week of fixes and polish across Grok.

- **Chat**  
  - The stop/voice button no longer flickers when you submit.  
  - Toasts are now centered over full-screen modals and on mobile.  
  - More robust multiline detection in the query bar, so inflight suggestions no longer pop in after you've gone multiline.
- **Skills & connectors**  
  - Manage your skills and connectors right from the composer.  
  - The connectors submenu stays open while you pick tools.  
  - Clearer tool-selection state for MCP connectors.  
  - Fixed a page freeze caused by the skills dropdown menus.  
  - The GitHub connector now separates App installation from OAuth.
- **Files**  
  - Uploads now surface a clear error when they fail.  
  - Disabled the PDF annotation editor that could crash on drag-and-drop.  
  - PDF quote and explain actions are hidden when there's no active conversation.
