No command line nor configuration required, just have everyone in the raid install this addon and the raidleader (+assists) should see all incoming notification and requests.

Developer notes:
This is a development project in live testing on Uldir.
BDLC uses a static scale with hardcoded naming. This fork defaults to a numeric scale and should be updated to support raidleader-pushed scales.
It also enhance the original addon in a few ways (trade filters, class filters, etc.).
It might, ultimately, be merged with the original addon.
