Wouldn't it be nice to see a new catmgr with drag & drop support to sorting the categories.
Also something like this for the albmgr, since it already is required to have javascript enabled?
I agree.
We could use http://code.google.com/p/nestedsortables/ (demo: http://www.bernardopadua.com/nestedSortables/test/widget/) for the catmgr. It's a jquery plugin.
Yes, that was my favorite too.
