    Default Two short Ext JS tutorials

    Hi, I've put two very short tutorials online with some c&p from the docs and source code of Ext JS 3.0. The goal is to make Ext users aware of a couple of new features that are not given enough importance or not yet fully documented.

    id vs. itemId
    What is the difference between id and itemId and why you should use the latter when possible.

    Using ref config option in Ext 3.0
    Using ref config to place a named reference of a Component into any ancestor Container. I think this one is a huge thing.

    itemId did exist for Ext 2, it just wasn't in the docs (I think feedviewer example had a brief comment about it).

    What do you mean when you say not documented fully yet? ref was added to docs, but apparently missed rc1.1 release.

    Your post is helpful, but I'd also suggest if you (or anyone) thinks something is lacking in the docs, to post in the doc thread so it might potentially get more easily added.
