Hi. Enjoying the project -- thanks.
Request: The ability to put DBM raid and instance messages in a separate chat window or channel. I have found this:

And the commands do work. I think it would be a nice addition to your already incredibly extensive list of options. Thanks again.

You can do this yourself without needing any addon to do it by following the instructions in the link you provided. Don't really think it would warrant a module. But thanks for your kind words!
