Checklist for Plugins

This PR adds highlights to the neo-tree.

• (In colors/melange.lua) Add highlight groups
• (In README.md) Add link to plugin source repository

Here is a screenshot I took showing off how the highlights I chose look:

Thanks for the PR.

I'd be happy to take the changes for neo-tree. There's just a couple of things that need to get fixed.

On the other hand, if nvim-navic doesn't set any default highlight groups, I won't add support for that plugin. Forcing every color scheme to add support for a plugin, when the plugin could just set defaults, is counterproductive. I'd suggest you send a PR to them with these highlight links, so other color schemes can use them.

I think I agree with what you are saying about navic, just removed all references to it from the PR including in the code.
