Personally, I almost wish Obsidian didn’t expose a folder structure - but the program is flexible enough to enable hiding the file browser, so that works for me.
Since TiddlyWiki doesn’t even mess about with the concept of folders, imo that forces users to dive in and really think about how they’re connecting notes through linking - which helps build a sort of mental roadmap through their notes. Roam and Logseq are similar, I believe.
Makes sense! I agree laptops tend to be too small for tiling; I don't really use the tiling part of i3 on my laptop very much - usually only to pop open a terminal window on the side that I close after a few minutes.
