I'm converting from Evernote to Dropbox/Markdown for my notes. And I really love the quick note capture menu bar applet for Evernote (image below).
Anyone know of something similar for plain text notes? Ideally it quickly stores the note as a .md file in ~/Dropbox/Notes. But .txt files can also work. This is on macOS Sierra.

I recommend NValt, a fork of Notational Velocity:

It doesn't work in the menubar, but you can configure a shortcut to show/hide the NV window if you want. It's also got a built in search, kind of like spotlight, which you can use to open notes quickly.
Here's a screenshot:
By default it saves the files in a database, but you can also save the notes in a specified directory as plaintext, RTF or HTML files. Or you can synchronize it with Simplenote (but Dropbox will work just as well if you use files/db). Markdown support is not first class, but it works when you save as RTF or HTML.
