It would be cool to have keyboard shortcuts to go to next/previous hunk of modifications.
I have absolutely no idea how to do it and even if this is possible with the SublimeText API.
The only think I can think of, would be to keep a track of what modifications are in the file at what lines, then see the cursor line position, then move the cursor to the first one after where is it at, or to the first if it is after all of them.
This isn't something I personally would want to work on at this time, I would probably accept a pull request though.
Although, what I think would be really awesome, would be to draw onto the mini map, the locations of the modifications, then you could jump to them by clicking on the mini map. I haven't had time to look into that though.
I'll have a look at feasibility. Jumping to next change would be ace for quickly picking up where you left off. E.g. "I was working on widget.py earlier, open and cycle through changes".
