Additionally (sorry for double post) I have a feature request which I'm not sure shoudl go in this thread or general WACUP feature requests.
It would be good to have a permanent "X" button to clear the search filter even when the search filter is empty, as in 5.666 I would frequently use this button to quickly defauly my library view to the top of the list. Currently, the "X" only appears if a search filter has been filled out, which is not always the use case.
