I used long miters on the legs, and I set my table saw to 44.9° to get a slightly better outer edge, but didn't fully consider the consequences. So the legs were slightly out of square, which made the sides, drawers, and shelves a bit squirrelly. In the future, I'll just set the blade to 45° and fill any gaps in the joint (or just don't use long miters).
Also learned that figure eight tabletop fasteners are stupid easy to install and work great. Got a bit more confident in building/installing drawers, which is something I've struggled with in the past.
