Suggestion: Modify url

[Alxandr]

I would suggest modifying the URL to maintain the state you need in your extension. Something akin to ?reposplit=.... I would put the file-tree status (what nodes are open), and what files are open in the URL, alternatively put this info in local-storage and put a "session-id" in the URL. That way, I can hit refresh and not lose where I was/what I was doing.

Great suggestion! I was thinking something along those lines with localStorage. Though the URL part didn't occur to me. I'll definitely give it some thinking :)
