That would be the ticket, unfortunately I can't locate it.
I can see all the individual save buttons, but the big one avoids me.
The point being that you get a visual overview of what's being rendered over time.
The current setup needs 3 mouseclicks and provides absolutely no visual cues as to which rendering is which.
I have to click click click and wait and then see whwteher I choose the right one....
If you are revising your rendering settings constantly the visual progression is immensibly usefull.
If you could couple that with a render setting history so that I could load render settings from an old rendering that would be first-class. Something like: rightclick old rendering thumbnail -> load rendersettings.
