Napkin wants to make the exploration of your ideas as joyful as possible. When you add a new idea it will immediately look for associations with all of your ideas. You'll see the topics below the idea when you see it in a flow.
However, especially when your account is still small Napkin might not immediately find connections. That's why, every night, your Napkin dreams: reconsidering all your ideas, more deeply reflecting which ideas are exploring completely new fields and adding new topics for them. The longer you'll use Napkin the better the associations will become and the easier you'll spot deeper patterns in your ideas.
Thanks for supporting Napkin. Now let's wish your Napkin sweet dreams π
