Feature Request: Indent nodes in/out as a whole

[sjmarshy]

I'm thinking the ability to maybe cmd/ctrl-left and cmd/ctrl-right a parent node, and have it's children indent further also. This would make adding a grandparent node much easier.

Thanks!

I would love this, including moving entire (collapsed) nodes up and down, but it's rather difficult to organise this in Codemirror functions. I tried this a while back but quickly gave up. A PR for this would most definitely be accepted.
