I'm in on Windows 2000. Active window titles that could be set to bright colors to distinguish the active window from all the others (mine was canary yellow). I miss you Win2k.
I don't have a Windows 8.x box to check on, but on Windows 7 you can still set the display attributes for active windows - it's just a bit more buried.

* Click on the Active Title Bar in the preview area, or
select Active Title Bar from the Item dropdown
* Customize the font appearance, including font, color, size and weight.
