Moblogging with Treo

So here is a post made from my Treo using mo:Blog. I like this app a lot, with its support for hi-res screen and html snippets. But the showstopper issue I have with it is its inability to let me choose different category when composing a post. Instead I have pick one catergory during the setup of the blog. WTF??? I won’t be that bad if it caches the category list for offline use but since it doesn’t that mean I’ll have to retreive the list OTA everytime I want to switch.
