Does LibreOffice have an answer to OneNote style documents? I know for a while in MS Office 97 there were obscure optional tools like Binder (that I used the fool out of ) and Equation Editor (that I never opened) - does LibreOffice have the same sort of thing?

Ever since Onenote 2010 got its cloud sync killed by MS when they deprecated cookie auth in January of this year, I'm trapped with Office 2016 and looking for replacement virtual 3-ring binder / organizer software that supports text, images, file attachments.

I am not going to OneNote UWP app or O365 for the same reason I am not trying Notion, the data is not on my computer.

I have a personal DokuWiki that I use for its purposes, but it does not support WYSIWYG or instant image/copy paste, audio recording etc.

A new application: https://github.com/blackhole89/notekit/ A more mature one: https://www.giuspen.com/cherrytree/

I know none of the ones mentioned match OneNote completely.
