no, the concept is broken in many ways. for one, if you have two monitors w=
ith=20
different resolutions, then at which coordinates do you position the panel=
=20
exactly? when doing things like "show only windows on current screen" in a=
=20
taskbar where the taskbar is split between screens, what do you do? what=20
about odd scenarios where the monitors are not left-right but top-bottom?

multi-screen panels work in pretty much exactly one configuration: panel at=
=20
the top or bottom with 2 or more monitors with the same resolution in a=20
left-to-right configuration. they break in every pretty much every other=20
case.

moreover, it keeps the code much more simple when it comes to things such a=
s=20
figuring out panel overlap/stacking/growing, the difference between vertica=
l=20
and horizontal panels, ensuring that applets don't hang halfway between=20
screens, etc... it's also one less option to take into consideration when=20
managing panel geometries.

you can, of course, put a panel (or multiple panels) on each screen. this i=
s=20
actually what i ended up doing when i used to have a xinerama set up at wor=
k.=20
even with kicker it worked better that way.

the only thing that works better with one panel on multiple screens is that=
=20
you could drag applets along the width of a panel without doing an external=
=20
drag and drop; so .... a fairly trivial improvement that isn't overly=20
annoying in the best of times.
