I've no problem with using LibreOffice for most of my document needs, but i haven't found a good substitute for microsoft's OneNote yet. I mainly use it to plan my RPG games and it helps a lot. What alternatives are there for organizing notes on linux, with similar features to those that OneNote provides?
Are you sure you are talking about Obsidian here? I can change the font size for both the editor and reader views, the default note name is 'Untitled' and markdown files are stored in plaintext.
I assumed you were asking what was wrong with the Joplin app, since that is what I was referring to in my post about awful android app. I use and love Obsidian on Linux, MacOS, and Android (tablet and phone). The only thing I don't like about it along the lines of my original reply to you is that task lists and to-dos aren't very easy or intuitive from Android. It's doable, but kinda clunky. So for that type of scenario I'm using Quillpad.
But no, Obsidian app on Android is great. Joplin…nope. :)
Oh sorry, I misread that. Thanks for the clarification!
