As of now, the module uses the BR- as well as the B-Tag when writing the state of a transaction into the comments of an order.
As those tags are not being parsed (neither in the customer-frontend or the admin-backend), I would like to propose the replacement of those tags with \r, \n, a combination of those or a "real" new like - depinding what works...
The B-Tag for marking test-transactions in bold would be obsolete - but this is no big loss, as it is not working now.
Additionally, I would like to encourage an update-procedure that changes already written comments according to this new style.
If I find the time to do it, I'll be glad to provide a patch of my own.
Regards,
Martin
