Web Design Brief
I need a UI design for an online code editor called Spritely.
Spritely is an online code editor for web developers, that aims to be an intuitive and beautiful editor that you can use on any device or browser. The current prototype can be viewed at http://spritely.io/editor
I am completely open to different colours and UI approaches, feel free to invent a new way for people to code :)
The final design should be something that is clean, elegant and functional. I will favour designs that are genuinely nice to look at and have a 'mac app' polished feel to them.
I have uploaded a psd that will provide a basic idea.
Go crazy, All ideas will be considered.

Requirements
Must have
- -Tabs: similar to chrome tabs, for different files.
-Line numbers
-The editor text area
Nice to have
- -An expandable/contractible file manager, on either side of the editor.
-Related files area under tabs. This is for quick access to files that have been included in the users code (ie jquery.js, etc). This will likely be expandable/contractable.
