No more obnoxious '}' on the cmdline when pressing `?`! scope: - More type hints - Added class Float for creating floating windows with size that fit the content and position centered on the screen - show_help action for outline window (key `?`) now uses a floating window - :OutlineStatus now provides better information, and shows content in a floating window. future: - Floating window option configuration
