Add fast way to reset parameter to default
The current code already contains some support for unlimited undo/redo history, separately stored for each tool. However this is not functional yet, so the corresponding GUI buttons are hidden.
When finished, there will be four buttons: 1/ undo last modification 2/ redo last modification 3/ reset to last saved state (the state is saved each time the controls are closed) 4/ reset all controls to their default values
However, I agree that it would be better to also have a quick way to reset a single control/slider to its default with a simple double click.
Point n.4 (reset all controls to their default values) is now implemented in the stable branch, at least for most of the tools. This new functionality still requires extensive testing.
