This is one of those things that is interesting but I don't immediately dis-like it like so many other ideas looking for a problem to solve. Being that it is so new, the one thing that strikes me immediately is the use of icons instead of text. I get that it looks good design-wise, but now my mind has to remember the icons. Some of the actions are short words where text could be used and not be cluttered: Move, Copy, Scale, etc. Maybe as an option?
Also, would it be possible to have a different trigger than keyboard keys? If I'm hitting keyboard modifier to enable this, I'll just hit the shortcut keys directly. What about middle-click (3-finger click on macOS multi-touch or something) equivalent to enable so that it is entirely mouse driven?
using text would lay bare the silliness of the radial menu pattern - it either wouldnt fit neatly into the circular containers or, if conformed to the curvature of the radial menu, would be unreadable/low accessibility
