[SnappleBoy]

You've all seen it, you all use it, you can't live without it and i can't find it:
The leftsidie Toolboxxy, popuppy, auto hidie, multiple panelly thingy!

I want it in my application but i don't how, where and how and where.
I've searched for this component d/l but found scratch,
Soo... if you know where to find it / how to code it... consider yourself challenged. please.

It's a really nice componenet, you can use it in your applications too!
In fact, when you'll have it, u'll use it all the time!
It's worth the bother! Code it!! Not for me, but for yourself!

Thanks.
