Planner - Suggestions / Ideas

I know we’re not far into the beta, but a few suggestions on the planner.

* Add / allow snap-to-grid functions
* Resizable nodes
* Node grouping. (Haven’t quite thought through it - but might be helpful? Possibly output an array of nodes?)
* Node color legend. Possibly customize it?

Just a few things I thought of while playing around today.

Add a hint of imp online status will be helpful. At the moment I can only get it from last connection time, since I am in the other side of the world, time translation is not straight forward.
