My suggestions/issues as I test the app:

- As spikefromspace says, it would be very good to see what are the actual capabilities of the app before downloading it. - Tag suggestions would be great. - Is there any way to save drafts not only in local, but also in the Wordpress blog itself?

I didn't find any bug, although the preferences panel opens in a different screen when in full-screen mode, it's a little bit annoying but no big deal.

With a bit more of work (for example, supporting rich text editing is a must) it could be a great app, and I don't know any other desktop Wordpress editor. Keep going!
