Suggestions to improve the painting tool : brush and settings
When I am doing extensive image editing, I am continuously changing opacity / brush size and sometimes other parameters. And switching between tool clone, heal, dodge/burn, smudge etc.
An important way to improve the experience, is to set up shortcuts/tablet express keys.
But I think the brush setting dock is confusing with a lot of widgets. I frequently use doge instead of burn and reciprocally because I forgot to check the corresponding checkbox.
Also, we cannot set up a set of brush settings. It is slow to switch from 10% to 90% opacity.
