The desktop app gives you a native macOS experience: a global shortcut to summon Slashy from any app, dock badge counts, system tray background running, and native notifications. Everything else works identically to the web app.

Key Features

Press Cmd+/ from any application to bring Slashy to the front. Press again to hide it. Works system-wide, even when minimized. Change it in Settings > Account > Global Shortcut.
Slashy downloads updates in the background. When one is ready, an Update ready card appears at the bottom of the sidebar. Click Update to restart into the new version, or Later to keep working.If an update repeatedly fails to install, the card changes to Update isn’t installing and explains what to do, for example freeing disk space, moving Slashy to your Applications folder, or downloading a fresh copy.
Open Settings from the app menu (Slashy > Preferences, shown as Settings on recent macOS) or press Cmd+,.
Slashy runs in the menu bar background, keeping email synced, notifications firing, and the global shortcut active. Closing the window with Cmd+W hides to tray (use Cmd+Q to fully quit).
Real-time unread count on the dock icon. Disable in Settings > Account > Show Unread Counts.
Uses macOS Notification Center. Respects Do Not Disturb. Control which labels trigger notifications in Settings > Labels.
Cmd+F searches text on the current screen — email threads, compose window, and settings.
Open a second window with Cmd+N — useful for keeping your inbox in one window and a thread or the calendar in another. Inside a window, drag a tab out of the strip to tear it into its own window, or Cmd+click a thread, label, or sidebar item to open it in a new tab without leaving the current one.
Press Cmd+Shift+T (or Window > Reopen Closed Tab) to bring back the tab you closed last. Each window remembers its most recent closed tabs.
Drag an attachment from an email or draft straight onto your Desktop or into a Finder folder to save it there.
Attachments save to your Downloads folder by default. Change it in Settings > Account > Save attachments to. After a download, the confirmation toast includes a Show button that reveals the file in Finder.
