While navigating through larger files of code I often use the undo buttons to jump to a place where I have been working before, just to check something or to place a bookmark.

Why not implementing a pair of buttons to jump to recently edited lines?

Option to automatically bookmark (or change color/highlight or symbol in margin) edited lines.

Another method...
Dockable tool that lists the most recent edited lines (Line# and first 30-50 characters in resizeable drop down list)
