Hi,
The search feature is broken in ABP's preferences window.
To reproduce: Open ABP UI where you can see your lists, and click the Search button or press CTRL+F. The search bar at the bottom of the pane no longer appears, so we can't search for specific filters.
I noticed the bug recently, it's a regression but I don't know how many versions it goes back to. Could be one or two, and probably no more than a year old.
Apologies if this bug has been reported somewhere already!
