I prefer the latter (current behavior), but your mileage may vary.

I don't care since I never use this list. I also think it is as designed.

However, currently the last "Filter" entry on the popup menu for items
listed with Shift+click that are already filtered out of the taskbar
(highlighted in the attached screenshot) does nothing. How about
changing that to "unfilter" so it automatically removes filtered tasks
from the filter list and so they reappear on the taskbar?

Your thoughts?

Well filter works to remove things from the taskbar so it a matter of which
way you think is more important. I suppose it would be possible to use both.
(ie if something is filtered the choice would be unfilter and if not filtered
the choice would be filter).
