Hi,
I like many of the icons for my own highlighting palette style, I found the following site and have use it extensively in my study of Revelation for my Precept homework.

Hope some of you will find it useful [:)]
eg. I have an angel (sort off) I overlap that with numeric number 1 - 6 to identify the 6 angels. (I import the following from L3, and have not look into the overlapping issue with highlight for "God")

Have fun!
