Option to zoom into nodes (should i work on this feature?)

Hi,

First of all this is the best JSON editor. I've used it in many projects! But there is one feature I really wish was there. The option to zoom into nodes to view / edit.

Right now when the JSON is big, it becomes very hard to edit with the whole thing open. So if there was an option to **zoom into a node and view / edit that node only** it will make editing much easier and cleaner.

I know some Javascript and would like to work on creating this feature but not sure if this need is specific to me or more people want this too?

What do you think?

Thanks,
san
