I use a different /viewpoint .. think mine is set to 0 0 1920 715 for my viewport .. so every thing thats covered up is the blackness of the edge of the game content screen I will show you.
Lianeb is correct, some of the different windows were pieces pulled from eqinterface which I further edited, along with all the default windows to remove labels, borders, add transparency, rid of specific elements I didn't want in each, etc. (The Station Cash/EQ button are hidden behind my loaded spells window which has a hotkey to temp go away in case I ever need to access them) The only things I think I've changed since that screenshot is editing the spell window to account for the additional slot and the buff/shortbuff windows to account for longer spell names.
The second image is of how the /viewport command shunk the bottom of the screen, (which is covered up by all my hotkeybars an what not any ways) and gives me a huge chunk of more viewable combat window on the sides ..
So when they do updates or such .. does it force you to go back into those files an re edit them to have the boarder-less windows an all that again?
EQinterface.com look for pieces most authors have Screen shots of them. Unless you are talking about timers. In that case turn them on in options
