Global Searches / Filters

Currently, filters and searches are applied to the selected folder only. I would expect them to be globally applied and be persistent, so I can browse individual folders and my filter/search criteria remain:

- E.g. a filter for green tags or a certain lens should remain if I change from folder A to folder B

Also: As the current filters/searches remain for the folder they got applied first, it means that if I browse away and don't reset the search/filter, I may forget. Coming back to the folder at a later stage, I only see a subset of all contained images. This confused me several times!
