I'd like to see more options for controlling diff context than None, Less, More, and Full. Going between Less and More gets me 2, 3, or 5 lines of context. That's just not enough. I frequently have to go to Full and then I find myself scrolling scrolling scrolling with some of the larger files we have on this project.

Why put a limit on "More", anyway? Have more/less just add/subtract 50% context and let the user decide how far out they want to go - 2, 3, 5, 8, 12, 18, etc. Or provide a drop down with a lot of options in it. It's really important to us to provide a lot more options than the 2, 3, and 5.
