Hello,

thanks for your quick reply.

This looks reasonable, the only problem I can think of is this setup:

  11112222
  11112222
  11112222 <-- taskbar spanning screens 1 and 2
  33334444
  33334444
  33334444

It's something that can be done for struts at the top and bottom of the root
window using monitor = 0xFFFFFFFF, so we might want to support it for inner
edges as well. I'm not sure if anyone actually wants to use something like
that. I'm fine with that not being addressed, personally.
