Yes, I'm being serious, this is a combination of a rich text editor with a code editor (more functionality, such as markdown mode, will be coming at some point in the future)

btw, you can press power+volume up to turn on the power menu without changing anything
still, just pressing the power button is easier for some people (me included)

It works but sadly doesn't show on lock screen for some reason...
I have no idea why xD
