[TxMt] Re: "Document.did-change" and access to the current document in a bundle?

[Jacob Carlborg]

From Allan:

"I actually have a local branch which allow commands to run on 
“document changed” which is designed for live HTML/Markdown preview, 
but could also be used for updating the gutter. Though there are some 
minor issues that need fixing before I can push this to master.” [1]

I’ve had some PRs for small things pending for a while, and I guess that the original author is no longer interested in the project. No problem there, my work continues and the plugin will soon be better than ever.
