• Easy integration with any project. Just addChild StablexUI to any Sprite or Stage.
• Separate "view" from "controller". Create all UI via xml (but you still can create ui with plain haxe);
• Compile time xml parsing. All xmls can be preprocessed at compile time, so your app is loading faster. Also everything is still strictly typed ;)
• Run time xml parsing. You can update UI in already published apps without updating whole app.
• Custom meta tags for xml to implement functionality you need, but wich is not implemented in StablexUI;
• Writing handlers (plain haxe code) right in xml;
• Really crossplatform! Works in cpp, flash, html5;
• Easy Drag'n'Drop;
• Relative positioning (you can define position by any border of element - left, right, top, bottom in pixels or percentage of parent's size. Define width/height in percentage etc);
• You can write haxe code right in attributes in xml to acces anything from anywhere! For example:

<Text text="'Hello world!'" x="flash.Lib.current.stage.stageWidth/2" />

• Easy skinning with 3-slice-scaling, 9-slice-scaling, tiling with texture, filling with color, gradient fill or your own custom skin processor;
• Flexible layout system (including custom layouts);
• Don't worry about forgotten eventListeners. Just use widget.free() method to let GC destroy the object;
• Ability to create custom classes for skinning, transitions, tooltips, etc;
