change reset filter behaviour of show/hide Track Browser

[jistme]

Request: Make it so that hiding the Track Browser doesn't resets filtering.

Scenario:

Have Artwork view.
In Track Browser select an item, so narrowing the filtering and displaying of albums.
Now if you hide Track Browser to get a better view of the filtered albums, it resets the filtering, showing all albums again.

Can it be made that filtering is reset when opening Track Browser, not when closing?

And to throw in an older request, any chance for a small button to reset Track Browser manually?
