I actually like her in season 4 (not completed yet), she was Clay's ex girlfriend and also witness in Bryce's murder and it was her idea to setup Monty, so yes, she is prominent character.

In the beginning of season 3, I don't liked her because she doesn't know Hannah and talk about her like she knows everything.

But, she is nice and was trying to help her friends.

I didnt like her

I never really liked her because it felt like a new normal character was interrupting the storyline who never went through what they did and yet understood.

I thought she was fine but unnecessary in season 3 and annoying in 4

In season 4...She definetly changed and I think thats what the writers noticed. No one at all liked her in season 3 because we'd just hear her voice 24/7 but then when she stopped telling shit to every cop in the town viewers started to like her. Sad thing is alot of hate came to the actor...Not the character.

She was amazing.
