OpenOmega theme

Hello.

I installed OpenPublic beta8 yesterday.

I want to make a working copy of OpenOmega so not to make changes to the original theme.

How would I do that? Where should it be copied to? Could I also add blocks to Structure -> Blocks or must all blocks be located via Structure -> Context? How to not have the demo info in that OpenOmega copy?

I want to make OpenPublic with OpenOmega easy to update in the future without overriding my theme customizations.

(Note: I need the answers/procedure for copying themes that are packaged with OpenPublish, also for the same reason.)

Thanks.
