Hi Carsten, thanks for the feedback! Let me cover your points in order:
a: We made the window larger to allow for a larger preview section. We received quite a few people asking why this was so small, so now it's larger. If you're running DisplayFusion on a lower resolution monitor, this preview section should scale down and allow the window to fit on a 1024x768 monitor quite nicely.
1. Removing the buttons wouldn't shrink anything, the listbox would still need to be taller than 1 button height.
2. I'd rather not decrease the preview window size, making it bigger was often requested.
b: Those icons are just place-holders for now, our graphic designer is working on some spiffy new icons, don't worry.
c: Being able to open the wallpaper window twice is a bug, I'll fix that for Beta 2.
d: WallpaperFusion will be available soon, we're working as fast as we can to provide the best integration possible!
I hope this covers everything, I really appreciate the feedback on the re-design. Thanks!
