I live in the wild pretty frequently, and I get mail fairly often (mostly from voting, I'm lonely) and I'm always curious about what is in the mail, even though I know I can't open it outside of /town or /shop. So my suggestion would be very similar to the chest preview feature, except it would only be for the user's own mail. The other awesome point about this feature, is that the mail reader could sort through mail that he/she finds worthy enough to actually receive at that moment, and whether or not you have the inventory space.I realize that one can go to another server and open the mail, but that's a hassle. In the times I've done that, I almost never remember that I opened it, and I have to scroll through servers to find where and I opened it.Lastly, is the vote thing good? I might've been a bit harsh, but I know some people on the forums just choose whatever response is the opposite of what the OP wants, regardless of their personal opinion. But I also don't want people to avoid voting because they don't feel like replying.
