Is it possible to use Sencha Cmd with a sandboxed build of Ext JS (e.g. ext-all-sandbox-dev.js)? I'm using Sencha Cmd

I think a config option like jsduck's
would help us here. I'm mainly interested in a build of our custom classes, so it would be ok to have ext-all-sandbox.js included.

Is something like this going to be implemented or will I need to migrate my app to Ext JS 4 before using Cmd?
