### Problem to solve When looking at a diff (e.g. on an MR), changes to submodules are shown only as the change in the referenced commits: **mylibrary @ `bbbbbbbb`** ```diff - Subproject commit aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa + Subproject commit bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb ``` While the heading is a link to the submodule project, it's hard to actually see what changed *in* the submodule. ### Proposal Simply add a link to `submodule/compare?from=aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa&to=bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb`. This will make it a one-click task to see what changed in the submodule between the points of reference in the super project.
