I used to have an Elantra that had the Altron Window Relay Kit. Essentially what it did was one touch raise and lower of the windows for all 4 doors from the driver's side (you could also stop it at different heights just by releasing the button or tapping it again). Another function of this that I loved was that when the power was turned off, there was still power going to the windows and it would roll up all four windows as well.
Here is a link and pic to what I am talking about just in case anyone knows of anything like this (searching came up with nothing for me):
