Do I understand correctly that paid subscription effectively removes 100 card limit? The description on the Settings page says something about "unlimited access to all content," but I can't seem to understand what this means exactly.

PS. I'm probably not the only one who stuffs his wallet deeper in the pocket upon seeing an "auto-renewable subscription." I would strongly encourage you to add non-subscription way for people to give you some money. I like what you made, it's useful and I'd like to support you, but no way in hell I'm entering a recurrent $ committment with a vendor of any app that I may or may not be using few weeks from now.
