Recursive compositing would be a very powerful feature, as would increasing the maximum resolution for the composite set up. A four-by-four scheme would make that j terminal possible. Composites of composites would allow for this and a staggering array of other schemes for custom bricks.

How easy would such features be to implement? Unknown to us, yet I wonder if issues involving the fontmortar (those unseen by us, perhaps hinted at by the rounding errors) make these features difficult to realize. They are otherwise so obvious and desirable from a user standpoint. Too powerful? Too potentially troublesome from a support standpoint?

Stacking of composite bricks seems to me the far sadder omission. The return on investment would be very high, close to that of the original brickstacking exploit. I want this feature, trusting it is possible with the same conviction that led me to first harnessing it.

Also, even bit by composite limitations, cool Bodoniesque font! :)

Even though it is not a perfect (and requires a reworking of the i) I suggest the following dots for i and j.

Yes, many times have I longed to be able to stack composites. Composites of composites would be even sweeter. :)
