I use org-mode for to-do lists, nested lists with to-dos scattered among them, scheduling stuff, and habits (repeatable variable schedule tasks). Orgzly does a lot for me already, and spacemacs+org-mode lets me edit however I want. I also use spacemacs+deft for quick notes, and org-capture for quickly entering new to-do items.
There's also the compact org-mode manual at https://orgmode.org/guide/
