Quote from xbeepsi'll merge it into main later today (currently busy painting the house!). Feel free to give Beacon of Light a shot, i haven't started on it. I did it once, but the code is gone, because when it was almost complete i found out that only effective heal carried over to the beacon, so i took it out again. As for Glyph of Healing Wave i don't think it's feasible with the current API, so i think it would be a good idea to consider how that could be accomodated for as an API change, hopefully without complicating the API too much (it's just one class and one glyph).
I'll do the Beacon changes on the test branch and let you know when I have something.
For the Glyph of Healing Wave, I was looking to find a general solution for those types of glyphs. I can easily see Blizzard creating new glyphs that increase the effect of a group heal on specific targets, like a glyph for PoH that also returns some of that heal to the priest, or one for Wild Growth for the druids. I'll think about it some more and share what I come up with.
