After examining the code, I found an issue with the user accounts importing module. Here is the problem.
B2 was released with some debugging code in the module, so...
When you select to import user accounts, and click the button to reset settings, you'll be presented with a blank window.
The good news is, it wont harm your existing data.
The bad news is... Your settings wont take effect because the action is redirected to alternate locations...
We should have a fix release soon, as the user import module is something we definitely need testing.
BTW, The code in the installer has been fixed as of now.
On a side note... I like the overall theme (with the exception of the initial wallpaper choice)
I like the style used in the theming... but the kicker for instance (the XFCE Menu icon) is too big, so it doesn't display very well @ 26PX panel height. Neither do the icons on the quick launch bar.
The desktop pager could use some gray lines to display where the desktop divisions are. It just looks like a big black box.
Also, the XFCE splash screen has a solid white bg... should be themed along with the rest of the theme. Prefferably with the bootsplash theme, because the bootsplash is still showing while the splash screen is displayed.
