Love the masking feature. To improve work flow I was wondering if it would be possible to add some sort of shortcut to mask a shape into another shape. Instead of going to the layer panel dragging a layer into another layer, it would be sweet to be able to do this on the drawing board.
For example, I have two shapes, circle and rectangle. I want my rectangle masked/clipped inside of the circle. I select the rectangle, press cmd+m (actual short-cut may vary) the short-cut activates the 'layer-mask selector' and my cursor now highlights all shapes on-hover. I simply hover over the shape I want, this case the circle— it highlights, I click on it, and now my rectangle in clipped inside the circle or in other words the layer masked is applied.
Hope this makes sense. This would be really cool and helpful!
