Just my two cents: while Joplin is made to be a coding application first, it should be equally friendly for those that want to put notes in Joplin. One of the reasons I moved to Joplin was because of its encryption. Unfortunately, Joplin doesn't seem to have easy access to features OneNote had - such as using Tab easily, as well as collapsible text. In OneNote, you could collapse any text that was tabbed underneath the text. All you would do would be to double click the left side of the main title and BAM, all text would be collapsed. PLUS, it would stay that way until you un-collapsed it.
