No doubt she should have appeared more often. If we didn't have inferring skills, then the entire medical staff of the USS Enterprise-D consisted of Crusher, Ogawa, and two Ensign Insignificants. However, there's a difference between the good guest stars, like Guinan or Barclay, and the bad guest stars, like a few of those ones that showed up just to spout out meaningless dross then hold the sets down for the rest of the episode.
And, as C.E. Evans stated, since I don't deny her rather attractive figure, she probably would've ended up as a Seven of Nine-esque character.
Also, if it helps, I believe she was in The New Frontier book series. But, books aren't canon, I know.
