In a post's revision history, every time I go to rollback an edit, I have to scroll up and down to figure out whether the link means "rollback this revision" or "rollback to this revision" (eventually accomplished by determining and then promptly forgetting, for the fifth time this week, that the most recent revision has no "rollback" link; thus, the latter meaning is the only one possible).
Could you please tweak the text to make it immediately clear what action will be performed upon clicking "rollback"? "rollback to here" would be fine…
