I'd like to see the mobile app bridge the gap between typical mobile note taking apps and the desktop Obsidian app. Make it easy to create a new note like you would in any other note app, save it where it makes sense to save it, make sync easy to setup, etc. Probably asking too much, but ugh... the mobile app is so bad.
The sidebar is just a tree in Obsidian. It doesn’t really act how I want. This is less an issue on desktop, but on mobile my expectations are different.
Hopefully sync setup has improved in mobile. That was awful last I tried it.
That's easy. Go to:
Settings > Files & Links > Default location for new notes: Same folder as current file
Note that the file explorer is a plugin like any other, so you can also create your own file explorer plugin that works the way you want it to :)
