. Make the Ctrl+Alt+Del screen a popup menu the size of the taskbar.
. Dim the screen slightly during important errors/messages.
. To save space, get rid of all exsiting Windows 98/XP/Vista icons.
. To save space, get rid of the Slide Show gadget, and merge the function in the WMC Gadget.
. Download Gadgets within the Gadgets menu, instead of through the Internet Browser.
. Add options pertaining to Gaming, such as stopping certain/all processes while playing games, or stopping the game process when in danger of a CPU overload, etc.
