Here's a feature I'd like to see....unless it's already included but I'm not aware of it. There are some occasions where I've made multiple changes to a project, but I haven't been happy with the result. I would like to be able to hit one button and "revert" to the original state of the last time the project was saved. Those familiar with Photoshop will know what I'm talking about.
Yes, I can "walk back" the various steps I've taken by hitting the "undo" button multiple times, but I find that somewhat unwieldy. Am I alone in this, or are there others who would find this useful?
