atm, the categories shown when a specific iconset is selected are all categories for all iconsets
The iconset temp has only got one category called Foo -
Please show only those categories that a specific iconset has (plus the All and Uncategorized)
In the next beta the empty categories will be faded out so you can tell which have things in them.
(Don't want to actually remove them from the list, as then your category selection would change if you switched through different icon sets trying to see everything in that category and some of the sets had nothing in it.)
