Feature request: Filter restricted cards, or pods

[Duckbringer]

It would be nice to have option to filter cards by their presence on restricted lists or in pod. E.G. if I type r:j the result would be cards that are on joust restricted list, r:m would result in meele restricted list, r:p7 would list cards in pod 7 and r:p would list cards in any pod.
If r is used for some filtre already some other letter could be used ofc.
