Jump lists serve me no use. I setup a Toolbar that I add everything I need to it. One click access. (2 clicks to launch a second instance of an app if it is "pinned")
As for Libraries, where is the option to remove them from the system, or just disable them completely? Oh you can't because M$ integrated them into WMA. I found that WMA all but requires the use of Libraries to work, so I had to use another program to listen to my music. I did find a registry hack to completely remove libraries from explorer which was very helpful. And if you want to free up real estate in explorer even more, you can remove Homegroup from there as well.
I love the performance of Win7 over any other previous OS, but the loss of "Classic" start menu and taskbar option is a severe disappointment. The option to remove/disable Libraries and Homegroup should also be made available. Windows explorer has become a complete disaster because of these features.
