Imported from CommOps Trac ticket #18.

Now that we have a lot more categories cropping up for the various subgroups and major topics in Fedora (e.g. Elections), the buttons for the categories menu seem a little large. For smaller windows, this can sometimes stretch close to off-screen (it's never gone over for me yet, so I don't know if or how it supports scrolling).

In either case, I think it would be a good idea to adjust the button height and cluster the categories closer together.
