I use helix editor for my markdown editor. Its use case is for the people that have no interest in configuring vim/neovim plugins. I would totally recommend it. Otherwise, you could use the kde editor Kate, or if you are a masochist nano.
helix-editor.com

My school orchestra only needed all black with a red tie, a tux seems kind of excessive.

Whats the difference between helixeditor.com and helix-editor.com, do you know if they are different projects?

I just switched to the testing repo and it worked. Thanks.
