I'm new to sencha touch and I've been browsing the kitchensink and other documentation, but I have not found any component that is the "slide out menu", which exists in many apps such as the facebook android app. Generally, the "slide out menu" appears when a user presses a button on the screen or drags the screen to the right or left, which makes the menu appear (please see screenshot). I don't think there's any component that does this? Ext.ActionSheet comes pretty close, but does not have the exact behavior I want. I wonder how I might go about making my own component for this?
