The second beta has been great. The first one was a bit too unstable to work on my messed up laptop but I have had no problems at all with beta 2.
The default fences are great. The recent items fence would be fun if that one was auto updated by what was actually recently used as time goes on.
Skinability would be nice but I worry over performance of that. If skins were just too much of a load, I'd like to be able to assign colors/transparency seperately to title bar, border, scrollbar, and background. Tinting each fence seperately would be nice.
Then there's stuff I'd like to see stolen from EverQuest II. Define the mouse over and mouse out transparency of all the items individually ( border, title, icons, fence background, etc... ). Icon Size/Icon spacing per fence would be a nice theft as well. Lock a each fence location individually. Lock a each dock icon contents. Go find an EQII player and ask them if you can play with thier back pack display settings.
Now for the fun ones. I would love to see different 'view as' options in each fence. Thumbnail, filmstrip, details (with sorting). Arrange icons by whatever in each fence would be great.
Keep up the great work!
