researching magic rings & amulets

Now we have "magical equipment", which gives 2 rings and an amulet; then "magical forging", which gives 4 rings & 2 amulets.  There's another ring later on.  So every time I get the the tech and want to buy the goodies for a key fighter, I have to remember (or check) which rings he already has.

How about someday rearranging the trees to be "magic amulets", then "magic rings", etc.  Just to make managing our procurement a little simpler.
