That 'elfy hangups' bit, though, seems like it should be a really major thing, at least for me. She's all about the little people, the people who are put down. But that amounts, from what I've seen, her essentially believing that elves shouldn't distinguish themselves from humans, give up everything that separates their cultures. It's hypocritical, and I"m certainly not claiming that companions haven't been hypocritical before, but there's no real opportunity for us to call her on it or see her opinions shift and change.
Her ranting about the Temple of Mythal proving the Dalish to be wrong was the first time that it came up in game for me, playing as a male qunari. For me, this felt like something that should kick off character development, a recurring conversational path through the game, placed at the end of a character arc. It just... it feels like if this was going to be such a major thing in her characterization, her dislike of 'elfy' things, there SHOULD have been more development. It just really makes her character feel half-realized and unfinished.
I will second the idea of a DLC expansion that gives her more, because as it is, she comes across as self-loathing for her own race, the kind of person who tells other people in her minority group 'stop being stereotypical' if they do the slightest thing that she considers stereotypical.
