It takes time to customise a system with picklist values, custom fields, custom page layouts & default saved user views (last two features are due very soon).

It would be great to have a feature that allows customisation to be exported from one database to another. Maybe there could be a copy customisation from Database A to Database B option. This feature would need to allow you to choose which customisation you need to copy. For example, you may want the picklist values and custom page layouts, but you may not want the saved views. There could even be an export customisation as a file that could be imported and run on another account (not just a from one database to another database within the same account).

I don't think records / object data would need to be exported as this is already exportable via the Export Database feature.
