I think I’m going to answer for both Olivia and Alt!Livia (or Liv, as I call her), if that’s OK.

* How I FEEEEEL about this character: I fucking love the original Olivia, for everything she is and chooses to be, period. I didn’t really like Liv at first, but she’s grown on me quickly over the second half of the season.
* All the people I ship romantically with this character: I ship Peter/Olivia and Liv/Lincoln, yeah I’m so original when it comes to shipping.
* My non-romantic OTP for this character: I am sure Olivia and Charlie are the best of friends in every universe.
* My unpopular opinion about this character: I don’t think Olivia and Liv are the same person. At all. Like, I often read ‘how can you not like Alt!Livia if you liked Olivia, they’re the same person!’. They’re not to me. I believe that everything that you have experienced, as well as the people you’ve met in life, shape your personality and makes you who you are. And they haven’t lived the same things, nor have they known the same people. Sure, they are the same biologically, and I don’t know what I reckon about innate personality traits, I think they can share some, but they’re not the same.
* One thing I wish would happen / had happened with this character in canon: I wish Olivia had not got together with Peter like she did (I don’t know how I’d like it, I just know that I didn’t like the way it happened). I also wish Liv had had more time to adjust to the idea that she was pregnant and even if she wanted to have the baby. I don’t know, it was too-sudden.
