When using plenty repositories the 1-level-grouping isn't enough to keep a clear view. Currently we use deeper directory structures on the server, e.g.
/scm/git/path/to/repository1 /scm/git/path/to/repository2 /scm/git/path/to/repository3 /scm/git/path/2/repository1 /scm/git/path/2/repository2 ....
but the grouping feature in the web interface only shows two groups named "path/to" and "path/2" and is not able to display this structure.
We would assume the interface to display only one top-level group "path" with two sub-groups "to" and "2" and so on.
