For an office suite, Calligra is a nice additional one to have alongside LibreOffice. Cons: Probably a smaller feature set compared to LibreOffice, and I'm not sure about compatibility with MS Office. Pros: is faster, more reliable, and IMO looks better than LibreOffice too.

FYI: some programs are a little harder to work out... For libreoffice I'll provide a link to the manifest for the Lubuntu jammy daily - https://cdimage.ubuntu.com/cdimage/daily-live/current/jammy-desktop-amd64.manifest Libreoffice largely has it's only libraries/toolkits; but you'll note two packages in the manifest that are definitely GTK+. I'd love to say there is no GTK3 in Lubuntu; alas it's not so. ... Source: over 2 years ago

Alternatively, you can use an online markdown editor like StackEdit or HackMD. - Source: dev.to / 4 months ago

Markdown is awesome! But, when writing 1000 words+ articles, I quickly feel the need for a better experience. For years, I’ve used StackEdit — an open-source, in-browser Markdown editor — for editing all kinds of long-format Markdown text. That said, given my recent experience with WYSIWYG editors, I thought I could do something better. - Source: dev.to / 11 months ago

This is especially annoying as when I export from stackedit.io to HTML, then it just cuts off anything which is outside the greyed in code window! Source: 11 months ago

StackEdit[0] pretty much perfected what I needed out of a markdown editor - I just need somewhere to write my tickets/docs that wasn't Github so that I could format it properly while writing. I still use it from time to time [0]: https://stackedit.io/. - Source: Hacker News / 12 months ago
