Screen space is used inefficiently: why is 50% of the screen width used to display player's names?

For that matter why is the whole "role assignment" overlay covering so much of the screen? Most people don't tend to look towards the absolute edges of the screen, particularly on large resolutions. The eye is usually focused towards the centre. I'm new to ARMA and the fact that I'd enter a lobby ("role assignment" seems unduly cryptic) was lost on me for a while.

Upon selection of a role, flashing white (Note that unlike bug 0004192, here a selected UI item flashes white immediately) does not blend well with the yellow colour of player names in the interface. The success of selecting a role is always therefore slightly unclear until the white flash has faded slightly.

Server Browser Filter doesn't remember filters between sessions. And why does it close the main server browser when viewed? I need to view both, so I can quickly hop in a preferred game if one becomes available.
