Hi @nikita.korobkin, thanks for sharing this, it’s a very interesting proposal and I particularly love the mockups that you have created!
We recognise that there can be some ergonomic improvements to the discoverability of friends’ cards, and already have a few enhancements in the works to make this a bit more seamless – one of these will be released in the next minor update.
Also filtering by Author should show all cards published and shared with you – let us know if this isn’t the case on your end. For example, I haven’t kept many of your cards from your digital garden but I can see all of your published cards if I filter by you as an Author.
Looking forward to sharing these updates with you and hearing your thoughts!
