I use Krita for everything, I love it so much. I also won’t act like it’s perfect either, despite it being my most used software by a landslide. Personally my biggest desire now is improved workflow for text editing (e.g. editing text directly on the canvas, being able to box and justify text, vector pathing for text so you can make it bend or wave). From what I understand it is something that is being worked on, and I will be even more indebted to the wonderful folks at KDE once further progress is made on that front.
If you tell them what you’re going to do, they’ll think you’re lying, thus ensuring the perfect opportunity to strike. Reverse psychology baby, it always works!
