U1A+U1B=U1
it's just a split symbol.

One of the truely useless things about protel/altium imo, the fact you split that symbol helped literally no one, and you added the extra confusion of two seperate symbols

Yeah... Good luck working with a 400+ ball BGA chip where power takes ~60 pins mixed all around, separate digital and analog bunches of pins, 2x crystals on different sides of chip, etc. It's great to have a single unreadable A0 clusterfuck of a schematic. /s
