Knitting gods, hear me now!

I'm so close to being finished with Thermal. So achingly close. See? All the pieces laid out on my bed? This sweater is wanting to be worn. It's willing to be worn, it's wanting to be worn -- it's waiting to be worn!

Unfortunately, there are a couple snags. Namely I hate the buttonholes and I just noticed some messed up stitches.

So, questions:

1. Does anyone know of any other style of buttonholes that are neater or ways to make this version neater? My buttons are are 3/4" in diameter, so I don't think a yarnover buttonhole will work. I'd love to do a vertical buttonhole, but it has potential to be a a pain.

2. What should I do about the sleeve? The only way I can think of fixing it is to cut the yarn above the places that are messed up, dropping down to fix them, and then grafting the stitches back. Fiddly. Reknitting the sleeve isn't an option. (Why? Because I say so.) It's not really noticeable unless you stare at the sleeve. Should I just leave it?

Ooh, fiber.

What am I eating for dinner? Four cups of air-popped popcorn and two tablespoons of butter. Eaten in conjunction with each other, of course. I'm not alternating handfuls of popcorn with little licks of butter.
