Hello. I want to suggest to add a Bone Selection icon in weight paint mode by side the face and vertex selection modes. It intents to be a better feedback on what selection mode the artist is using. Now it is like having only face and edge selection icons for mesh editing but not vertex because it is the "default" tool. I know the bone selection is not a mask tool like the face and vertex selection, but, at the end, all 3 are just selection modes for the artist workflow.
