Whenever I get a thought, that there is something I want to do later and my laptop is not nearby, I open Obsidian on my iPhone. Immediately, my daily note is displayed and I can add a todo or task. To open the app, I have to unlock my phone and navigate to the app.
A simple lock screen widget, that opens the app directly. This would reduce the navigation overhead when writing down short notes and make the process more seamless.
