Letterboxing Mail.app
I’m not sure who came up with the three-pane system most software mail clients (and some web clients) use, but I’m desperately curious as to what they were thinking. It’s one of those things we don’t normally think about because, well, we’ve just been using it forever and gotten used to it, but how many times have you had to fiddle with that middle divider to get just the right amount of body showing and still be able to see more than a few e-mails. It just doesn’t make any sense to cram two fields that need to be long on top of each other. Enter Letterbox .
