Is there an open-source collapsible #
outliner out there that uses the following style with proper indentation?
I. Main Point
A. Subpoint
1. subsubpoint
a. subsubsubpoint
I have #
LibreOffice, but it's not collapsible and I'm looking more for an app and document organizer. #
Obsidian has an outliner, but as far as I can tinker, it only uses the asterisk and hyphen for subpoints and not letters and numbers. #
Zettlr seems to have similar limitations. Maybe I've just not figured it out on these apps ...
#
TiddlyWiki does a fair job, but only uses numbers and symbols and not letters.
