Yeah having the keys change for each program is so nice. I’ve had trouble building up configurations for all the programs I’m using and then learning those configs so I find the GUI really nice.

There’s no logging of the keys being pressed. There are hooks installed on top of the keys configured to be re-mapped and the key used for toggling but these presses aren’t logged anywhere. All the configuration is stored in plain text though so you’ll want to be careful about what you put in there.
