The menu bar

The menu bar icon is the app without the window. It starts and stops the current preset, switches between presets, shows how many controllers are connected and what the engine is doing, and carries the Emergency Stop. In menu-bar-only mode it is the whole interface most of the time.

The menu bar popover.

Menu-bar-only mode

Settings, Advanced can hide the Dock icon. The app then lives in the menu bar and the window opens on demand. With launch at login on and per-app auto-switch set up, it becomes something you set once and stop thinking about.

Questions

Why does the status show CPU use?

So you can see what the engine costs at the current polling rate. Idle should be near zero; a running preset at 240 Hz uses a few percent.

Can I switch presets from the controller instead?

Yes. App Action outputs include Next Preset, Previous Preset, and Activate a specific preset, so a button can cycle layouts.
