I spent a bit of time with MyPaint to work on an actual piece rather than just random doodles.There is an almost hidden function in MyPaint that allows you to sample a stroke in your artwork and the brush and color setting for that stroke propagate to your current brush.
This means I don't have to cycle through brushes or keep tabs on what ones I'm using, in this instance, after realizing I was only using about three brushes, it was easy to just select them from the artwork and continue working.
