Suggestion: write a Docushare-Slack integration that looks for the patterns of LSST's Docushare document handles and posts back a small snippet with the document title, a Get link for the document, and a ServicesLib/handle/History link for the version history.
Should recognize all commonly used LSST handles (i.e., all the L?? handles, Document, Collection, Minutes, report, etc.).
May not be practical to implement before the Docushare v7 migration. (Is there a ticket for that that could be linked?)
