A widget for android that shows an editable version of a set page or a daily notes page. Maybe have it show the Preview of that page on the home screen, then switch to Editor view if you click on the page to start editing/typing.
I don’t know what other community members think of widgets, but for me, widgets make or break a mobile app. It would go a long way to making it possible for Obsidian to replace my note-taking and todo-list apps. It would probs end up being the only thing on my home screen lol.
