what's wrong with being able to size your icon as big or as small as you want?
isn't that huge icon sizable?
if so, I would put my most used lin in the middle as big as that so I can click without aiming, and a bunch of satalites progressively smaller as my reap estate gets used up
this is a good thing and I don't think it's overkill at all
If it were me, I would make it so the user could make any icon the size of their entire screen and allow them to resize accordingly
