I'd like to be able to see changes I've made to a file in a branch other than master. Is there a way to do this?
Additionally it would be really nice if I could diff between the heads of multiple branches, eg MyBranch's HEAD and master's HEAD.
All the heads (branches) and tags are listed on the project summary page (/?p=yourrepo.git;a=summary). Gitweb doesn't currently support diffing the full tree against another commit.
