Please can I make an app suggestion.

I noticed that the mobile web browser and app are different and there is a feature on the mobile web browser that I think doesn’t exist on the app which would really help my use and enjoyment of the app.

Please can you add to the app the ability to filter by course type / provider ? I want to use LingQ to study what my language exchange talk friends send me (import) but I also want to be able to use LingQ for discovering my own content - and I would prefer to be able to filter not just by context (which the app already does) but most importantly by media type.

I have different preferences for different types of media and it would really help my enjoyment of the app if I could easily filter between text, video, and audio, on the fly - as I enjoy each type at different times - walking, eating, sitting in the evening on the couch - please add this!
