Hi. This is a really helpful addon, thanks for creating and maintaining it.
I've come across an issue using the announcer module. If the "healer forget timer" is set too low, it can easily lose track of healers while defending a base, for example, and if set too high, it tends to remember healers from previous battlegrounds. Would it be possible to automatically reset the healer lists upon entering a new battleground?
Also, I think it would be helpful to have an option to list the classes of the healers in the announcement message.
