So the reason I am looking for a DM feature is not so much that it becomes a chat, but often you do see requests to be DMed for furthering a conversation offline - say for jobs or projects etc. And often this results in hunting down the "target"'s email from their profile and firing up an email client etc. Yes a very first world problem but still was hoping for a slightly easier way to do this (short of writing a browser plugin). I do like @remyp's app idea but it still requires me a few "redirects" mentally.
