This is the Default Player Window with some changes.
1) It is a fixed size.
2) It has added these features: AA exp bar, Exp bar , AC , Tribute Timer, Inventory slot 8 and powersource slot (for timer purposes).
3) Also Included are 2 optional Window Backgrounds (from a Sars File) Replace the default window_bg_light_rock and dark_rock with the files included if you like that look.

Everything I tested works. Enjoy!

(edited to include my new border and title bar changes)
