I tried installing Telescope, picked up the .deb from the garage, but wouldn't let me install it as I had not installed something called "libimlib2", although I have no idea where to get the file, a cursory Google didn't turn up much. I will keep looking.
My app switcher key (which I was also previously calling the hardware minimizer button) goes dead with Diablo5 just simply installed - whether or not the theme is active.
