I imagine you've figured this out by now, but anything in the ovi repo is categorized under "user/hidden" which is why they aren't getting put into the correct categories. Perhaps you could scrape the ovi store, or use RPC/JSON?
Just installed it, looks great. Will manual edits to /opt/catorise/menu to change the categories of some apps be overwritten in future updates, or is there a more preferred way to do this?
So we need somekind "refresh the menu" -button or otherwise it should be done manually by some background process?
