Describe the feature

1. Add recursive searching of media, so that media in sub-folders is also shown in a search
2. Do not hide folder when a search is in progress to allow navigating through sub-folders and back to the main folder

Additional context

On point number one above, if it is thought this in not what the majority of user will want then this could be a configuration option. Possibly a check box by the search bar that remembers the setting until it is changed.

The current media search in FS is cumbersome to navigate media folders when a search is in progress. Since it is not recursive and does not show results from sub-folders nor is it possible to navigate to another folder while a search is in progress, many times a search must be done multiple times in multiple folders.
