The dev team have also talked about the planned changes for version 1.9:
We’re currently hard at work with WordPress for WindowsPhone 1.9 – the next major release of the app. The most important to-do in the 1.9 road map is Featured Image, improvements on the Editor Page, as well as a few more nifty improvements.
The client, which can log on to existing Wordpress.com sites and self-hosted Wordpress installations, is a free download from the AAWP app directory or the Windows Store.
