 = (function) returned function accepts a single numeric parameter that represents z-index of the handler. It is an optional feature and only used when you need to ensure that some subset of handlers will be invoked in a given order, despite of the order of assignment. 
 > Example:
 | eve.on("mouse", eatIt)(2);
 | eve.on("mouse", scream);
 | eve.on("mouse", catchIt)(1);
 * This will ensure that `catchIt()` function will be called before `eatIt()`.
 *
 * If you want to put your handler before non-indexed handlers, specify a negative value.
 * Note: I assume most of the time you don’t need to worry about z-index, but it’s nice to have this feature “just in case”.

/*\
 * Element.transform
 [ method ]
 **
 * Adds transformation to the element which is separate to other attributes,
 * i.e. translation doesn&rsquo;t change `x` or `y` of the rectange. The format
 * of transformation string is similar to the path string syntax:
 | &quot;t100,100r30,100,100s2,2,100,100r45s1.5&quot;
 * Each letter is a command. There are four commands: `t` is for translate, `r` is for rotate, `s` is for
 * scale and `m` is for matrix.
 *
 * There are also alternative &ldquo;absolute&rdquo; translation, rotation and scale: `T`, `R` and `S`. They will not take previous transformation into account. For example, `...T100,0` will always move element 100 px horisontally, while `...t100,0` could move it vertically if there is `r90` before. Just compare results of `r90t100,0` and `r90T100,0`.
 *
 * So, the example line above could be read like &ldquo;translate by 100, 100; rotate 30&deg; around 100, 100; scale twice around 100, 100;
 * rotate 45&deg; around centre; scale 1.5 times relative to centre&rdquo;. As you can see rotate and scale commands have origin
 * coordinates as optional parameters, the default is the centre point of the element.
 * Matrix accepts six parameters.

 | // translate 100, 100, rotate 45&deg;, translate -100, 0

 | // to reset transformation call method with empty string

Opa,

Claro que seria possível, porém exige tempo e estudo em como integrar =]

Isso aqui daria um post bem grande. Existem outras bibliotecas que podem ser integradas para melhorar a interface de graficos e componentes...
