That did it! This is awesome, thanks so much! I spent the whole day looking for a solution to this. This solves my problem, though I guess it's still worth asking - you wouldn't know of a way to make the list item width unlimited (or set a higher a limit to it) so that items names (window titles) are not truncated to start with?

Anyways, great work, hats off !

Alternatively, is there any way to make the list wider so that longer items fit in it, and that way, the tooltips won't show anymore (I noticed they don't show when I hover over a list item that short - shorter than the overall list width)?
