The IDR name is long enough to seem unmanageable.  Is it so because we are
concerned about clashing?

[stevenjb, 2015/02/06 17:50:30]

I would suggest that the CR_ELEMENTS_TOGGLE_BUTTON bit is unnecessary. We should
name our custom elements uniquely / descriptively.

[michaelpg, 2015/02/06 21:32:02]

I thought it was just convention to use the path. We don't have to worry about
clashing here.

[stevenjb, 2015/02/09 18:33:00]

Thinking about this more, I would keep the CR_ELEMENTS, but remove the redundant
TOGGLE_BUTTON.

Done.
