I think there should be a space in the settings dedicated to what the BTT process is allowed to listen for to decrease it's impact on input lag for certain apps. I don't use any mouse gesture modifications from macOS default, so there is no need to listen to the mouse or trackpad at all. I just want a few keyboard shortcuts. Please consider this. One app in particular is the game OpenRA. Running BTT introduces major input lag. Even with the priority tool.
