Transparent Prop Backgrounds
Some 'shape' props are transparent, and others are opaque. In the gallery, there is no indicator of whether a given prop is transparent or opaque. For example, if I choose a circle prop, will I be able to see through the middle of the circle to the underlying objects? Three part proposal:
1. In the gallery, provide an INDICATOR for each prop about whether it is transparent.
2. In the gallery, let the user FILTER by transparency (yes/no).
3. For each shape, let the user CHANGE the transparency after dragging it onto the canvas. (turn on / turn off)
