Description
Currently all of the symbols are generated as boxes, this was to make things easier when generating the symbols due to lots of them having unknown numbers of pins.
However, for readability, it would be useful to have an alternate body style that more closely matches the function of the cell, like what xschem has.
Implementing this would be easy enough, it would involve altering Cell to take a symbol body and having pins being named appropriately in the symbol body template. The downside is that quite a few variants of the symbol templates would need to be made.
