This was already made, is on Github, called overlay, however it doesn't work (at least for me)
Also, no offence to cantlookback (person that made it), but the UI doesn't look too good.
An idea of mine would be for it only to be shown when a button is pressed (maybe next to discard button)
Would do it myself but I have no idea how to code. (trying and failing to learn)
I've attached the code for what they did.
Also is it bad that I'm copying someone's idea? Sorry, it is pretty old tho.
