Your one-stop
publication workbench

From idea to publication in one app: Zettlr accompanies you while writing your blog post, newspaper article, term paper, thesis, or entire book.

I prefer using separate software for notes and to-do lists.
So, for to-do lists I use Joplin (on the Linux PC).
For long and knowledge base notes I use Zettlr (on the Linux PC) and for quick and encrypted notes I use Standard Notes on the Android Phone (it's available on F-droid).
