Extend the empty taskbar (tasklist) to the right edge of the screen with the panel stretched to 100%.
Hello Xfce Panel developers,
the xfce-panel currently contains a module (tasklist; taskbar) that does not yet work satisfactorily. With a 100% extended panel, the taskbar is not extended so far that the other panel elements to the right of the taskbar have to be prevented from moving the taskbar to the left by a separator.
A possible solution would be to include an option in the taskbar that extends it until it either reaches the right edge of the screen or the other panel modules placed to the right of the taskbar have reached the right edge of the screen.
However, without the limiting separator, all panel modules to the right of the taskbar move to the left and do not remain on the right edge of the screen as intended.
So instead of the additional separating element, extend the taskbar.
