I use Quiver[0] ($10) to store and organize work and personal notes. Their "cells" of content can be written in plaintext, code, markdown, or LaTeX. You can organize with folders, tags, favorites, etc. The different viewing modes are perfectly flexible via toggle-able panes and a "presentation" mode.
The db is just a file you can choose to sync however you want. I use Resilio[1] to keep work/laptop/desktop machines in sync.
