Some suggestions on "Mask Editor" and "Shortcuts".

[ZXCMiller]

All parameters on the right side of the Mask Editor interface have to be set each time they are opened, rather than retaining the parameters set last time, which makes it particularly troublesome to use, and there are no shortcuts to use similar to the "Liquefaction" interface in Photoshop, for example: brush size can be controlled by "[" and "] ".
With respect to Shortcuts, there are a few features like these that don't allow for custom changes or additional key controls, like if I wanted to start a workflow task from a custom button on my mouse.
