What’s your PC trackpad/keyboard application of choice?

I went on a frenzy of trying out a bunch of different ones a couple of years ago but wasn’t satisfied with any of them. They all had weird display bugs, or problems maintaining a connection, or were just straight-up too ugly to use.

I don’t care about fancy features like special interfaces for individual applications or whatever. I just want something that isn’t cluttered, looks nice, starts quickly, and works.

Thanks in advance for any and all suggestions.
