Fbpanel on multiple monitors: how to filter displayed application per screen?

Based on my earlier question and answer from Arkadiusz Drabczyk , I have set up 3 different instances of fbpanel, separate one for each of my 3 monitors: This is how I start fbpanel: fbpanel -x 0 --profile left & fbpanel -x 1 --profile center & fbpanel -x 2 --profile right & The 3 profiles left, center and right are defined in my ~/.config/fbpanel/. The profile center contains definition of the taskbar plugin, ie the active windows currently open are visible on the tab, and can be switched between (alt+tab) or "minimised" Plugin { type = taskbar expand = true config { ShowIconified = true ShowMapped = true ShowAllDesks = false tooltips = true IconsOnly = false MaxTaskWidth = 150 } But the taskbar on the center monitor contains all applications (from all 3 monitors). So I have one taskbar for 3 monitors. I would like to have one taskbar for each of my 3 fbpanels, where only applications currently occupying left monitor would be on the left fbpanel's taskbar, and so on So basically, if I move application window form center monitor to left monitor, the application currently "docked" on the center fbpanel's taskbar should move to left fbpanel's taskbar. I have no idea if this is possible. More details to my setup: Im using fbpanel in openbox, my OS is Debian Buster. I would be happy to recompile the fbpanel package, if that would solve my problem.
