I write this with a spinning wheel of death in the background.
When Fusion hangs and lags for what seems to be an indefinite period of time, and you find yourself staring at the unfeeling spinning wheel of death and knowing there is no way to take back control other than a force quit. Instead of potentially wrecking your hard work for the gamble it was saved, what about a "force quit process" using the "Command . (period) keys"? to stop the last command and regain control?
This would be very helpful and much appreciated.
...and now to force quit Fusion and hope that the work was saved.
