We went on a 2 week trip soon after my last post, and we've had a lot of fun with Pipsqueak since we returned. While she only came out early ONE TIME for our neighbors replacing her food during our trip, we stay up later, and she's at least started to come out between 10:15 and 10:30PM now, which is way better than before. Additionally, she is so adapted to coming out. I've had to split time between her Omlet playpen (which I LOVE by the way- so much better than any of my cheaper options in the past) and supervising her running around a bedroom or bed, because she's just become so trusting with us and comfortable coming out, relative to how timid she was for the first 2 months we had her.
I also upgraded her wheel from the 10" Bucastate to our old 12" Silent Runner. I feel like the wheel part wobbles a little under her weight when she runs on it, but everything seems to be tightened properly and she doesn't seem to mind. In fact, since I brought that wheel out, she spends a LOT more time running on it. I even carry it to and from her playpen. However, when she decides she has a way out of the playpen and she's had enough of what we have in it, she will just repeatedly try to climb out

Of course, she can only do this when one of us is sitting in there with her. She also readily climbs on my hand and up my arm now if she wants assistance leaving her cage or another space, and that's now I know how comfortable she is with us! Of course, I still use a transport for long moves for safey.
Note: She really just wanted her wheel in the first few days we upgraded her wheel- she very much wants to explore still!
