If I haven't a choice, then I want a light theme. Dark themes are notoriously difficult for those of us with any color blindness issues (a significant portion of the population). I have a very slight red/green color blindness and even for that slight degree of impairment, dark themes are problematic. But, I still want a choice!
As for the bottom panel, most people have wide screens these days, and it's vertical, not horizontal, real estate that is at a premium. I always turn the bottom pane off to increase the vertical real estate, both for the editor and the side bars. When it's needed, it pops up on it's own, anyhow.
Is there a link to an explanation of the 'commando' feature? I've yet to be able to get a functional version of the alpha running on my system... it fails to start up codeintel.
