Since I started to thinker with private Mastodon threading, I’ve been experimenting with using Mona as a private note-taking app.
Hiding the Home tab from Mona makes the app feel more private. I only left the following tabs available because I want to optimize it only for my posts.
I read other people’s posts in Reeder; I use Mona for threading and journaling about ideas privately (and keeping up with my notifications and mentions).
Another thing I did is to replace the ⌘N keyboard shortcut with a custom Keyboard Maestro macro which creates private posts by default. This way, I can work on my threads in a private manner, but still see my notifications if I post something public.
These changes make Mona a note-taking app with built-in discussion features. I don’t know if we have any other app like this.
This is one of the things I love about the Fediverse. In essence, it is just a public place where we post things, but we can make weird mashups on top of it, like a note-taking app.
