UI - Have the shape/mask cursor reflect which shape is currently toggled
Simple one! ...if you tap Q to select the mask/shape tool, and it's set to rectangle, rather than just a crosshair cursor, it would show a crosshair with a little rectangle. Tap Q again to switch to elipse, and the cursor changes to crosshair plus elipse. never again would we tap Q, drag a mask... and oops I was already on the shape tool, I wanted a rectangle but got an elipse. ....why not implement on all apps?
