I love Obsidian, but it’s more of a replacement for OneNote, Evernote, etc. Having said that, almost everything that i write is for myself. I don’t really publish anything for anybody else’s consumption, so pictures, colours, fonts are a bit of an afterthought for me. I did knock out that git presentation the other day, and managed to do that in Obsidian. I’m a little strange though… I’d rather write a document or presentation in Markdown than Word or Powerpoint. Once upon a time i would have used LaTeX.
I did get into CryptPad for a while, but it wasn’t really ready when i tried it out about two years ago. I liked the security of it, and i liked the self hosted apps too. It seemed like a fantastic alternative to Google Office. I remember that i had migrated a spreadsheet that i rely on into it, and it then got munged, so i had to roll back to a backup and play catch up on a month or so of updates, so if you go down that path, tread lightly. It was super cool though, so if it’s ready now i’d love to hear about it.
I’m using LibreOffice for that one spreadsheet that i use. I’m also using SyncThing to replicate it across my devices. Excel opens it seamlessly when i find myself on my work laptop which is a bonus.
