Seems to work quite nicely so far. One thing I don't like is the cursor resetting back to the top of the list when you do something like change the region of a save. But otherwise I have found no problems so far.
As for the look-and-feel you asked about... I'm generally one of the those who likes the default look (and I use a classic theme, which I much prefer over the XP look). Maybe you could have an option to adapt to the current OS theme (current behaviour), or allow skinning? That way everybody is happy...
