Thanks for this! All actions works great on Kubuntu 18.04 Minimal install.

For future updates/features, I'd like to suggest the ability to adjust the colours of the button ("standby" and on hover).
Also, with the "minimize all windows", when minimized, clicking it again to "unminimize" would be neat, like with "peek" (Show desktop) :) - May 14 2018
