I will do that. If there is no action from me after a couple of weeks by all means step in and take the initiative. What I plan to do first is to alert some contacts that I believe will have informed opinions and be interested in this discussion (though strictly speaking it is an announcement rather than a discussion), in order to see whether there are fresh ideas to incorporate. At present the pool of potential 'up-voters' (if that term can be used as a compound noun) on UserVoice will be very small, so the plea here is one of 'please do not do anything that may stymie future development'. From JoeMcDaid's response we appear to be in safe hands.
Something I didn't dare suggest for the longer term is to build upon pivot table concepts to create dynamic representations of multidimensional arrays, which can then be used in formulas. More mundanely, I would love to see array formulas replace the automatic user response of 'copying formulas down' which, in the main, is just a cheap and cheerful way of expressing an array relationship.
