Hmm well theres a few....
1. The ability to have all my icons next to eachother in the taskbar when its pinned to the right of my screen with out having to do it through the quick launch folder trick.
2.Completely hide the time / date and all the icons with the click of a button that would open and close it.( I just look at my keyboard for the time ( G15) )
3. Ability to center your start icon and all your icons to the center of the task bar.
4. A better search. I had to run diskmgmt or somethign along the lines of that and It wouldn't pop up until I completely typed out the entire program name including the file extension
5. Windows Media Player / Center to support MKV =P
I think thats it for now just minor ones!
Curious to see what others have to say!
