Ability to mark letters as part of a word you can’t complete yet
A lot of the time I’ll see a lot of letters that I know make up a word later once I’ve solved part of the puzzle. I should be able to mark them as a different color so I know I can ignore them in my search for another word. I suggest a long hold on the first letter (3 seconds) to trigger this feature.
A great idea, I'm definitely with you on this one
