Power users of CurrentKey have requested a faster way to jump to specific Rooms. Arguably setting hotkeys for specific Rooms (a feature since v1.6) will always be the fastest way, but otherwise, clicking the popover dropdown is too slow. [App Store link]
Enter Room Explorer, which displays to the left of the pop-up with a list of your Rooms, presenting quick info (last visited and usage time) and a button to take you to any of your assigned Rooms!
You can enable this feature in the Preferences pane of the app.
