@ramob It's a typesetting markup language and the software to parse it. It's more designed for producing papers than taking notes, but I think it'd meet your needs given the other software you've used for the purpose.
I switched from Texstudio to Latexila a few years ago. The canonical recommendation for people who like WYSIWYG entry is Lyx.
@khird thanks I'll have to check it out!
Part of why I was using markdown was it had a pretty easy flow to memorize but I'm curious to try that now too. I'll have to check my repo for those.
@khird I've heard whispers of it but I have not looked to far into it. Is it a language of sorts to organize notes? What IDE do you use with it?
