Actually, the Poser interface is a lot more customizable than you think.  In the thread where people were guessing at what reason 7 would be, this topic came up.

I'm at work, so I can't look at it right now, but you can change your disply colours and all the icons exsist as (pngs, jpgs, bmps, I can't remember), but the point is if you don't like the icons, you could even take them into an image editting sofware and change them and then either place them in the same place witht he same name (backing up the old ones, just incase) or you could go into the xml file (again, not infront of my computer and can't remember which file off the top) and change where it is pointing to for the icons.

Set up you pose room as you like (ie: delete figure, set up two white lights, move aroudn you icons) and then in your prefences tell it to save current state.

If you are so inclined, you can even change what picture is displayed while booting up.

It is extremely customizable, you just ahve to look around a bit.

Cheers.
