First time setup
Three minutes, including the part where you can't find the icon.
1. Install
Open the DMG. Drag Day Slip into Applications. Eject the DMG. That's the whole installer.
2. Launch
Open Day Slip from Spotlight (⌘ Space, type "day slip") or from the Applications folder.
Nothing visible happens. There's no window, no Dock icon. Day Slip lives in your menu bar — the strip at the top of the screen, next to the battery and Wi-Fi.
3. Find the icon
Look at the menu bar. You should see a small checklist icon — by default red, configurable to any of ten colors.
Fix: hold
⌘ (Command) and drag any visible menu bar icon to the side. The hidden ones slide out. You'll find Day Slip among them.Or install a free menu bar manager like Ice — it shows everything that's hidden and lets you reorder.
4. Use it
Left-click the icon — the task list opens.
Right-click the icon — settings and quit.
Default global shortcut: ⌥⌘T opens the list from any app. Change it in settings.
5. Open at login (optional)
System Settings → General → Login Items & Extensions → add Day Slip under "Open at Login".
If something looks broken
The first launch from an unsigned build may trigger Gatekeeper ("Apple cannot verify…"). Right-click the app in Finder, choose Open, confirm. After once, it just opens.
For everything else: open an issue on GitHub.
