### TODO

- [x] Make sure keybinding shows up in pane + menu
- [x] Selection tool in the editor toolbar
- [x] Application Menu
- [x] Add more options to pane + menu
   - Go to File...
  - Go to Symbol in Project... 
- [x] Add go items to the selection tool in the editor:
   - Go to Symbol in Editor...
   - Go to Line/Column...
   - Next Problem
   - Previous Problem
- [x] Fix a bug where modals opened from a context menu aren't focused
correclty
- [x] Determine if or what needs to be done with project actions:
- Difficulty is that these are exposed in the UI via clicking the
project name in the titlebar or by right clicking the root entry in the
project panel. But they require reading and are two clicks away. Is that
sufficient?
    - Add Folder to Project
    - Open a new project
    - Open recent
 - [x] Get a style pass 
 - [x] Implement style pass
   - [x] Fix the wrong actions in the selection menu
   - [x] Show selection tool toggle in the 'editor settings' thing
- [x] Put preferences section from the app menu onto the right hand user
menu
- [x] Add Project menu into app menu to replace 'preferences' section,
and put the rest of the actions there
- [ ] ~~Adopt `...` convention for opening a surface~~ uncertain what
this convention is.
   - [x] Adopt link styling  for webview actions
   - [x] Set lucide hamburger for menu icon
   - [x] Gate application menu to only show on Linux and Windows




Release Notes:

- Added a 'selection and movement' tool to the Editor's toolbar, as well
as controls to toggle it and a setting to remove it (`"toolbar":
{"selections_menu": true/false }`)
- Changed the behavior of the `+` menu in the tab bar to use standard
actions and keybindings. Replaced 'New Center Terminal' with 'New
Terminal', and 'New Search', with the usual 'Deploy Search'. Also added
item-creating actions to this menu.
- Added an 'application' menu to the titlebar to Linux and Windows
builds of Zed
