For the daily use of Stock, especially with a bigger team, it would be very valuable to have a filter within the search for the already licensed/downloaded pictures/videos etc. So that you could still use every filter and the normal search. With this feature, Stocks could act as an easy image database.
The license-view is not useable for this as the pictures are way too small, you need to hover over those to see it accordingly, and you have only 10 pictures per side.
Also, the marking of already licensed pictures is really hard to identify and could be optimized.
