Ah! All right nice! Thanks for this change! :D

If a Set is selected, only the selected one will be displayed in the filter options, until you select All Sets again. Guess thats a limitation of the change? I dont know ^^ If Im too nit-picky, Im sorry, dont wanna be annoying!

Thanks for adding that! But after testing this right now, I think its currently broken: Selecting something different than All Sets will show an empty collection. There are no sets listed in the filter only "All Sets" and you need to switch to something different and then back to collection to show everything again.
