Taking away features in Photoshop for vain automation and like this doesn't already cost a lot
A) No 3D now?! (GIMPand InkScape are free, by the way.)
B) Paint messes up freaky style once zoomed in, on a new computer too.
C) Lost library content, and custom patterns and presets after update
D) No way to delete pattern list headings when they start multiplying with repeated content in them four or more times with the bug-filled updates.
