I'd say she appears quite extensively in OoT, TWW, ST and SS. And in the other games, she is very important to the plot, even if she only appears in person a little bit.
Of those, I'd say she only appears extensively in ST where she is dead. She certainly appears in SS, but not to an extent that I'd consider her significant. In TWW she has about as much total screen time as Link's grandmother, and in OoT she just... really isn't there.
