Moving the eye to the right is what you'd want because it'd shift the player's mob to the left.
Right, I had it backwards. Because the right side of the screen is missing 32 pixel of horizontal space the whole map looks like it's being eaten up by the output panel. The output panel just looks a lot bigger than it actually is. Optics be weird, man.
You can change how much the eye gets shifted to keep the player's mob centered in the view, even when things block parts of the screen (like when you open your inventory in Diablo). A message log seems like the kind of thing you'd always want there, so I'd just make buttons to toggle its size.
The same could probably be achieved with child panes but, it would be a pain to set up because splitters only accept percentages rather than pixel measurements.
Having partially transparent interface elements (like this thread) seems like one of those things that people think they need (because other games have it), but having it wouldn't actually improve their game. If you have a terrible game, having a message log obscure part of the screen is just another problem.
While I agree with you in saying a bad game is a bad game regardless of its snazzy interface, this would be a really nice feature to have. If you combine it with this feature I could probably rebuild Decadence in a month or two and it would run twice as smooth.
The percentage of the screen that's covered isn't the only factor. Place the message log in the center of the gameplay window and it'll be even more game-breaking.
