Oh yes this. Throbbing shrines! Seriously, I can never remember where I have emblems waiting and I don't enjoy checking every shrine for them. I guess glowing would be ok too :)
I've often wished for something like this as well. I think having the emblem peeking out of the top of the shrine could work really well, too, since you can't donate while you have a pending emblem. It's clogging up the works!
