Obsidian Canvas was released today and I find this very exciting! As you might know, I'm a very visual thinker and try to organise my thoughts in ways that are more intuitive to me. I've always thought that an infinite canvas that you can place nested collapsible components and primitives on makes much more sense than a directory tree. I've used other tools for this, but the separation from my PKM tool (Obsidian) has always been a big barrier.
Obsidian keeps getting better over time! It seems the canvas format is relatively simple, where I reckon I could have these be publishable. More importantly though, I think it would be quite useful to organise my thoughts internally. Currently I use a combination of whiteboard wallpaper, actual paper, and Samsung Notes on my S22 Ultra; the only not-bad Android note-taking app with good stylus support, but frustratingly it doesn't let you scroll the page infinitely in the horizontal direction!
It can be a bit frustrating to try and manipulate a canvas without over-reliance on a mouse, but I don't think there are any ergonomic ways to interact well with these besides a touch screen, and at least the keyboard shortcuts for Canvas seem good. When AR becomes low-friction, I hope to very soon be able to use 3D spaces to organise documents and assets, in a true mind palace. For now, Obsidian Canvas will do nicely though!
