This may be a no-brainer, but I'm a bit clueless... Up till recently AppCode showed markers in the left en right side gutter of my editor window for all edits I made. Color coded depending on what kind of change, and a nice revert/show previous menu.
'All of a sudden' it's gone and I've know idea what happened or what I have done to disable it. (I do know by now I rely heavily on these markers ;-) Problem is that I have no idea how this feature is called so it's bit hard to find useful info. (Yup, searched the forum and googled.)
Any hint greatly appreciated!
