I'd like to see...

An XP-style (32-bit color) icon would be nice, just for the taskbar, program/shortcut and system tray.

Maybe XP-style interface icons too, but those aren't as necessary.

Well u can always make your own toolbar icons and replace the default ones... it's not really difficult, just copy & paste some XP icons and/or search for icon libraries...

Well, he wasn't talking about toolbar buttons.
