The first two things I mod out each alpha are Trader closing time and protection zone. This lets me keep my own schedule, and I really don't see any added gameplay value from traders closing. It's just a nuisance, and I can still see him standing there. Open the door, @%$#.
While I would love an option for this, lots of folks would like lots of options for lots of things, so I don't expect the devs to spend much time on it. It takes five minutes to do it myself.
