Tips – Adult Coloring Book! Review

I really enjoy coloring this pictures. I am new to this app although, I have other apps I am coloring. I would appreciate the three (3) tips shown after downloading the app, to be available for future reference. I am unable to undo or clear a color if I should decide to change the color without resetting the entire project. Thank you
