Craig suggests to support use of the colour scheme from pg 146-148 of the dissertation, and therefore to provide a way for a user to select a starting order when writing sentences in a rule.

See pages 146-148 (Section 5.3.3.3: Making the Syntactic Structure Explicit).

I'm imagining a drop-down list with coloured rectangles in various orders to select from, as in Table 11 (pg 148). Each combination can then be followed by a list a languages that commonly use each order.

Sending first to Calvin for throughts.
