The width of the Working Area list displayed middle-clicking on desktop
is severely limited for no reason, preventing enough of the window
titles to be seen when they are long enough, which has a very major
effect on the usability of the feature.

This is a bit variable, since this list is displayed with a variable
width font, but it more or less displays only 22 characters from the
title. This is clipping 5 out of 10 windows on my desktop at this time.

It makes no sense to place a width limit on this list, since the space
needed is variable, can be actually a lot, and it's not known in
advance how much is needed. If anything only preventing the
window from being larger than the screen is necessary.
