I speak as a Code::Blocks lover, so this should not be read as whining.
One of the most annoying tasks in my work (Code::Blocks is not unique in this) is to be able to move from point to point in code and get back to where I was.
Example: I'm tracing a problem and my program calls a function, so I right click and Code::Blocks takes me there.  But... how to get back?  What file was I in?  What function?  Of course, I can remember this for one level, but try three, four or more levels of this and it's a pain in the ass.
So I propose a WayBack feature, perhaps presented as a tree-view in the manager toolbar.  To use WayBack you'd set a "waypoint" marker.  Then, as you stray, you set another one, and so on.  Waypoint markers might be seen similarly as bookmarks, only they are sequential - or chained together.
The tree view would let me jump back to any previous waypoint, and so on.
I'd also suggest that a hotkey would let you jump back to the previous waypoint, and another to go forward.  Successive keypresses would go back or forward a single step at a time.
Perhaps a simple function key would clear all the waypoint markers, and a right-click context or hotkey would let me clear the one I am on.
(The only other thing, and this is a longstanding annoyance, I'd do is put a copy/cut/paste in the right-click context menu.  But this is out of the range of my topic!).
