[ADDED] Please enable undo

for the love of all that is good - yes!

A single level of UNDO!

The number of times I've had to unload and reload a model and rebuild supports etc etc because of a SINGLE mouse slip-up is ridiculous! Such powerful, feature-rich software simply can't lack the most basic feature of all. Like a fancy car with no reverse gear, there will be too many occasions where users end up in a corner with no way out. The users are human and to be human is to err. Ergo - UNDO.

Please?

Undo functionality has been added in the latest version 3.0 release of the software. If you ever accidentally remove a support structure that you didn't want to or accidentally remove a process you didn't mean to, just go to Edit > Undo (or use standard Ctrl-Z shortcut). It's a life saver
