- Design principles doc is badly out of date, needs to reflect lessons
  learned and things observed about where the game is headed.

- Less cumbersome scaling controls.
	- Use loitering or staring, or some other passive input
	  instead of a pummel recipe.
	- Should hopefully make the process feel more natural.
	- Need multiple handholds (i.e. ceil+wall version) since
	  player no longer picks the surface.
	- With no death/respawn, and no fast-travel, we need to
	  buff player movement to balance that out.

- Hint system updates.
	- Need a "witness" system for spontaneous in-world processes,
	  such as tree growth or lode cooling.  Credit players within
	  a certain distance and line-of-sight.  
	- Feedback/issues URL?
		- Look for new URL buttons in 5.0+

- Reinstate and update toolbelt once engine PR #8701 is released
	- Alternative item strategy with dedicated slots for each
	  inventory space, which can be empty if in hand instead.
	- Consider a "backpack" approach as opposed to toolbelt.
