It would be nice if I could just hide all the stuff that does not do it for me.

Hello,
Could you please give a few examples ?
Thank you

@FrostFeely

answer based on Stable release (not Beta)

for hiding complete cards...
on each card (when you open it's page) there is an eye symbol on the card. Click that symbol and the card image will go blurry... it is now hidden. To view hidden files, click COLLECTION and in the top right you will see an icon of 3 sliders. Click that icon and select Hidden cards... to go back to your normally visible collection, select Full collection

for not viewing clips...
open the clip manager (on each card) and deselect the clips you don't want to see.

for more specific help, you need to provide more info (as @Manue said above)

I think @FrostFeely is asking for a way to permanently filter out unwanted cards with specific clip types from the store.

some filter that prevents these cards from showing up in the store, or being won in the TGIF events.

@FrostFeely would have to give more specific details as to what type of filer ( the Criteria ) the request is about.
