The more frequently a feature is needed, the more valuable it is. And the more valuable a feature, the earlier it should be implemented.
On the other hand, the more frequently a feature is needed, the less UI gestures (clicks) it should require.
Therefore there should be a positive correlation between click count and iteration number for each feature. This could probably be a useful user experience metric.
If only it was possible to calculate this from automated tests and the backlog...
