Leave 'compare' button pressed on choosing another snapshot

Currently, to compare multiple snapshots with the current document, I should click the ‘compare’ button each time I choose a snapshot. But when I want to skim through what has changed over multiple snapshots, it would be desirable to keep ‘compare’ mode on, so that I can just press up/down key while I’m on the snapshots list, without clicking ‘compare’ button each time. I will be able to focus on the change, rather than on clicking.

The implementation will be simple – just leave ‘compare’ button pressed when the user chooses another snapshot. It will make the already-great snapshots capability awesome!
