Multi-tabbed JavaScript Code Editor (IDE) in RealBasic/Xojo

Before apply, please make sure you have strong knowledge or RealBasic/Xojo. --- I'm looking for someone to build basic multi-tabbed IDE for JavaScript editing. IDE should have dockable sidebar, log bar, menu bar with basic functionality like file operations, editing. Code editor component/tab must have syntax highlighting (if you can handle some intellisense, would be a plus). Tab operations, like Close All, check if code was modified before closing and offer to save changes. --- To confirm that you understand the idea, please provide a screenshot of basic layout and brief information about you and your skills.
