I'm not sure I dare make yet another suggestion but I do so in the hope of being helpful rather than critical.
For the past couple of hours I have been trying to refine Wipe and Auto-Dev settings.
So for example in Auto-Dev I keep trying the ROI in different places with different sizes to see how things change and I really want to be able to compare the current change to the last one, rather than to how it looked before I came into the module. Obviously if you just did a Wipe and go into AutoDev the "Before" button doesn't help much. Similarly with WIPE, for example I would love to be able to see whether reducing Aggressiveness helps to retain nebulosity.
Perhaps an additional "Before" button that just compares the last action?
