I'm a STORYBOARD ARTIST and I REALLY LOVE GOODNOTE'S Pencil tool!
But for a decent Workflow I need to make THUMBNAIL DRAWINGS in BLUE or RED first and then LATER INK THEM in BLACK on top.

Therefore I would EITHER need a SELCTIVE COLOR ERASER, and/or a
SELCTIVE COLOR LASSO..

I then could ALTER the BUE SKETCH below , by either changing it to a different color, that'a not as visible ( a light GREY for example) OR erase /delete it ALLTOGETHER, with my BLACK Drawing intact!!

That would be a GAME-CHANGER for my workflow and would imitate a more sophisticted drawing app like apple notes or even Procreate in THAT regard..

But I really would like to do that INSIDE GOODNOTES! 🙏🏻👀 Thanks!
