I don’t know what they did to the Flow/Opacity thing, but I kind of like the Flow effect. Same brush, different opacity/flow setting.
I can now quickly access my most commonly used brushes. A quick note on the Eraser brush: You might be wondering why even bother when eraser mode is activated via the “E” key. Well, Some brushes takes a very long time to perfectly erase because of its brush’s tip/setting. You would have to go over many times, and it can be frustrating if the size of the brush is below 5px. With the actual Eraser brush, one stroke and it’s gone.
You can now quickly change these.
