Can we get a new input type? – Pixelogic - Daily Nonograms Review

I’d love if there was a second input mode that we could use as a “what if” scenario. Sometimes I get stuck and want to take a guess at what the correct spot would be. If I guess right, then great, but if I guess wrong I have to backtrack and don’t know what squares are right and which ones are wrong. If we could have a second mode with say, blue squares and X’s, then I would know which ones to backtrack to.
