1. I mean that would be a good idea in my opinion, but that's not what I meant, I meant something like the button reuses the image next time it says edge.
2. That's fine if you'd rather do that.

Ok I get it now! It is possible, but having too many buttons up there is also a problem. Since you can already stay on the same picture by clicking back (or pressing the <- arrow) when it changes, it's probably best not to add a button for this one!
I will however add the "back" button for all modes.
