Merge Request > Changes Tab > Side By Side. Add the ability to expand the code around the diff.
In Inline mode it is possible to expand the code by clicking the "..." by the line numbers. It would be nice to have this in Side By Side
Alot of times the diff is just a few lines, and when doing code review it is helpful to expand the code above or below the changes in order to get context of what is going on around what was changed.
