Help needed with collapsible menu in Sencha Touch App

[Blitz2]

Hi,
I am making a web app wherein I am trying to make a collapsible menu(not actually making one, using a workaround ). What I do is on tap of an arrow, an overlay sheet appears. The sheet has another arrow docked at the top.
1. I want the sheet to slide out on tapping of the docked arrow. I need something like the show() method for the sheet to gracefully exit.
2. Right now, I am removing the sheet and destroying it, which removes it from the screen, however the earlier arrow needs to be tapped twice the next time to render the overlay sheet. Any ideas or is it a bug?

Any help is greatly appreciated.
Thanks.

Swarmonline has a great series on how to make a plugin. Essentially any behavior that can't be done directly through the native sencha touch library can be added using plugins.

This helped me a lot in doing what I need.
