Create widgets for Android and (assuming possible in iphone) that shows a page on your home screen. The page should be user selectable and default to be “Contents” page. Should be able to see the contents of the screen at a glance and when clicking on the widget opens the page for quick capture.
SimpleNote has a very good implementation of this as shown below:
Something like the Todoist widget would be amazing. Instead of showing the daily Todos, just show Todays note, with a + button to quickly add a bullet/TODO. See: Add a Todoist widget to your Android home screen
For others who land here from search looking for this feature, I have a workaround that I use on Android.
I installed the open-source Markor app (available in the Play Store and from F-Droid), which has a “QuickNote” feature that can write Markdown. Go into Settings > General > QuickNote and navigate to a note inside of your Logseq’s “pages” directory that you want to be able to quickly add notes to (I use one called “Inbox.md”, for example). Now you will be able to long-press on the Markor app and select the QuickAdd button (lightning icon) and you’ll immediately be able to edit that file.
Makor works well for this because it reads/writes Markdown and it has a built-in file system navigator. It took me a long time to find a simple notes app on Android that had all of this, but if you know of another app, by all means, use that one.
