This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository.
The flags filtering was moved from a menu option to an embedded chip view triggering a separate bottom sheet dialog. Contains some code from commit 4254250 that was about flags filtering. Note: see the changes in CardBrowserTest.checkIfLongSelectChecksAllCardsInBetween(). For some reason after adding the tests related to flag filtering, this test started to throw NullPointerExceptions which also triggered another test to crash as well due to unhandled exception from another test. Using a position that should be displayed seems to fix this.
