Currently I save keybindings.json, settings.json, ~/.vscode/extensions, ~/.config/Code/User/snippets and ~/.config/VSCodium/User/globalStorage/alefragnani.project-manager/projects.json in my dotfiles to backup vscode.
The documentation says:
Following UI State is synchronized currently:
- Display Language
- Activity Bar entries
- Panel entries
- Views layout and visibility
- Recently used commands
- Do not show again notifications
Which file(s) shall I backup if I want to backup the UI State in my dotfiles.
