It is difficult to identify which preset has been applied after some additional tweaks have been made. So, why not save automatically an auto-version with the name of the preset each time one is applied, so we could later check how we arrived at a certain edit.
Also, on a similar note, when applying a preset, we could add an option to "save as new version" or similar, so we could later compare different presets on a same photo. The use case here would be we create a bunch of different photos with different presets applied to later compare, rank and tweak.
