Feature request: Undo

[Former user]

Hi,

Please incorporate an "undo" command, a buffer that allows reverting the deletion of the input box command.

Regards,

[Alister Hood]

Of course, if you use Ctrl-Z and Ctrl-Y you’ll see there is already an undo buffer (maybe provided automatically by Qt?), the problem is that “Edit-Clear Expression” or [Esc], don’t work with it!
