Hi,
@Fabio : first, this is a complete off topic. If you want to start talking about this, add a new thread in the "whatever you want to talk about" forum...
secondly, you're not a developer, and I don't think you have much right to request stuff like that as you don't really know what you are talking about. Gus made a very clear explanation (thanks for that

) and I don't think it's as easy as it looks to you...
About chameleon, there are plenty of screenshots, if you just took the time to look at the thread about chameleon before asking those questions... we wouldn't be wasting time here...
@Auria : you never used Tcl so you don't know how easy it is, maybe you should give it a try before cursing it....
