Re: Thoughts on the standardization of Org

[TEC <tecosaur@gmail.com>]

I feel that this also ties into my earlier idea of putting Emacs
as/inside an LSP server for Org.  I suspect there may be a a lot 
of
potential in making it dead easy to use Emacs as a tool.

I'm rather busy over the next few weeks, but I'd be happy to 
spearhead a
project in this direction.
