WordPress has great functionality of categories but I thought it has room for improvement. For example, I open 3 categories, one for Google, One for MSN and one for Yahoo! and then realise that I would be better off with a single one called Search Engines, then it would be nice to have a feature called Merge Categories.
Also, if a Delete a Category, everything goes to the default, which sucks. Can we get a choice, as to which category does it goto?
