uuid and entity import / export

Hello guys, I'm a developer from Adyax company. I think that Backdrop it's a really cool idea. If you do not mind, I would like to offer some features. Would be great if backdrop could export / import (synchronize between sites) a certain nodes, taxonomy terms etc. Like it is possible in drupal via module Universally Unique IDentifier (https://www.drupal.org/project/uuid).

For example in the entity object we can have configuration parameter which will say us, should we save this entity into json or not. And make possibility to export / import them manualy.

Also would be great if we could add a node display as block into layout.

In my opinion it is realy helpfull features because we use them in all our projects.

If you are interested in this, I and my colleague could start work on this.
