Fullskrin: show text on full screen [please roast]

I created fullskrin back in 2015 to do one thing only: show any text on full screen.

The idea was born at a hackathon. We wanted to write "Looking for a designer" on our laptop screens during the coffee break and no one on the team knew how. At least not on any OS and within seconds.

Obviously, this is not a business. I've just joined IH and wanted to post something. Any feedback or criticism is very much welcome!
