While ibisPaintX is a great program for people who can’t afford other programs like photoshop, csp, procreate, etc or don’t have PCs or tablets that can run those programs, it can still be improved.  Many artists spend hours working on their drawing and even the already light grey background of the app can be too bright for some people to look at for long periods of time.  Having said that I think dark mode would be EXTREMELY beneficial for all users.
