fix(gutter): enable mouse events for tooltip#42
Merged
Conversation
Add transparent background to gutter margin Canvas so mouse events are properly captured. WPF requires a Background to be set for hit-testing to work.
- Remove Git Graph, File History, Line History, Compare commands from menus - Remove Git Graph settings from options page - Keep stub command files for future implementation - Remove unused command ID constants
- Create Git Ranger submenu under Extensions top-level menu - Move Toggle Inline Blame and Toggle Blame Gutter to submenu - Remove "Git Ranger:" prefix from menu items (submenu provides context)
- Replace WPF ToolTip with Popup for reliable dynamic tooltips - Add TextChanges CommandFlag to allow Enable/Disable text updates

Background = Brushes.Transparentto the gutter margin Canvas.In WPF, a Canvas without a Background property set will not receive mouse events in empty areas. This was preventing the tooltip from appearing when hovering over the gutter margin.
