The menu bar and Settings
Droppy has no main window. Its menu bar icon and its Settings window are where you configure it, and both are reachable from the surface itself.
The menu bar icon
The icon opens Droppy's own menu: your active Droppy Cloud shares with a delete button for each, Voice Transcribe's Quick Record, High Alert, the Basket, Settings, and the update check.
You can hide the icon entirely under Settings, General, and bring it back by right-clicking the notch silhouette where it used to sit.
Opening Settings
Right-click the notch or the island to open Settings from anywhere. What that right-click does is itself a setting, under Settings, Accessibility: open Settings, or hide the surface until you right-click the same spot again.
Settings has a search field of its own. It searches every setting on every page as well as the Droplet catalogue, so if you know roughly what a thing is called you never have to remember which tab it is on.
Dock icon and launch at login
Droppy runs without a Dock icon by default, which also keeps it out of ⌘Tab. Turn the Dock icon on under Settings, General, Startup and visibility if you would rather have it. The same card holds Launch at login, which needs Droppy allowed under System Settings, General, Login Items.
