Further enhancements for authoring

[TheBizzle]

Just to get this documented somewhere, there are a number of things that I didn't address my initial draft of the authoring/interface-editing functionality for NLW. The ones on my mind are as follows:

• Making plots editable (and then createable)
• Automatic resize/reflow of widgets, based on their content (like happens in desktop NL)
• Multi-widget move
• Multi-widget delete
• The existing touch control don't really seem to be operable in Safari
• Possible improved touch controls

People can pick up items from this list as they see fit, especially considering that some of this stuff really isn't very difficult.
