The future of Obsidian is Canvas because building notes is time consuming. But Canvas can be used for solving complex problems, especially creating ambitious non linear stories where the complexity can go to astronomical degree. Movies like Primer is a great example.
I like cards but I have to zoom in each time to see what’s in the cards. So having a bold title with one or two words to quickly remember would help. Or when we click on a card, summary will be displayed on the right hand corner.
Also adding all keyboard shortcuts in the software itself like how they do in Google sheets would be helpful. I can hardly find the answers when I google sometimes.
