7/10
I would love to help but I haven't used GIMP in a long time and don't remember how to do everything.
9/10 oh, ok, I think I'll explain anyway though X3 I'm not sure what happened, but I got a popup(or something) that came up so fast I didn't even see, I was clicking on a brush at the exact same time, and all of a sudden the brush-changing options, size-changing, everything below the color wheel is gone, replaced by a message "You can drop dockable dialogues here"
