first off, thanks for creating this (and also the S60 version).
Have you looked at PyQT or PySide for using the QT stuff with your exisiting code base?

and now some observations or enhancement requests;
* offfline mode

* default when starting up?

* store posts, drafts locally and then sync up (this works on the S60 version already?)

* use more "standard" icons on the post edit screen

* follow wordpress, media wiki, blogger etc conventions ( "globe with chain" is the insert link icon, bold is strong B etc)

* any way to get "tool tips" or text?

* remove publish icon. Change it to a menu option, and add a save as draft option as well!
* allow selection of blog when saving drafts or publish

current method only posts to whatever is set as default
