Everything but chat fits nicely in the bottom 20% of your screen. Unzip the file into your GUIProfiles directory, and choose the appropriate aspect ratio for your screen.

Chat remains in the top left, mission tracking in the top right as well. All hotkey bars fit across the bottom of the screen (1 & 2 stacked in the center still, 3 and 4 to the side in two rows. Companion & companion cast bar is still in the same spot, and the minimap/tooltip combo is larger now, to match the width of the left side. The companion hotkeys are now 2 rows just above the castbar, and a spacer before the party/operations windows. Player and Target frames are lowered a little but unchanged for spacing. Each one has their castbar moved beneath them. Focus target/castbar is above and left of the player frame, and target of target/castbar is above and right of the target window now. Party target frames are enabled for all party members.

PVP objectives are nested inside the mission tracker now, and holocom notification is at the top of the screen now. I left the menu items in place; I think they say, "Hey, this is Star Wars!" even though the only time I use them is to edit my UI without pushing ESC. I shrank the XP bar and nestled it under the menu items. Lastly, the secondary windows are movable, so you can have you character sheet, inventory, crew management, and crafting all open at the same time.

It's possible to drop the party/raid frames down enough so that Party Member 3 and your companion quickbar share the same space (since you'll never have both up) but I like the separation of real-estate, plus I like my party window to grow up, not down. My main character is a tank, but I currently have a 50 Guardian, 50 Marauder and 50 Commando, plus a 40 Shadow, and I love this interface on all of them.

I made a version both at 16:9 resolution (1600x900, 1920x1080), and 16:10 resolution (1440x900, 1680x1050). If any adjustments need to be made to the 16:9 resolution I'd appreciate feedback. I have both XML files in the dowloaded ZIP file.
