When I paint I need to change sometimes brush presets. The icon for brush presets is less attractive or visible to hit, than the icon which shows the brush engine. Intuitively I hit very often by mistake the brush engine. It's possible to exchange both icons or to make the brush preset icon more important for a quicker, more intuitive use?

If you submit a better icon to represent the brush preset selector popup that still fits in with the icon theme, we could consider that. But what you currently propose is not feasible: the icon used in the preset editor represents the current brush engine.
