• SC4 has slightly better transient response. QB3 has better F3. Both are useful, but if you can only have one, QB3 is best, IMO.
• SPL phase for a box design isn't very useful, but since it comes along with the transfer function perhaps just a check box to enable/disable would be useful. Group delay is often desired, but I think few understand it enough for it to be really useful. Not terribly hard to add, though.
• Some sort of step/impulse response widget could be more useful
• Driver/Vent/PR displacement and velocity for a given stimulus, Max SPL (excursion and thermal limit, whichever is less) both are useful and easy to add.
• Dual voice coil support.
• Auxiliary filter alignments, passive radiators and 4th order bandpass (just a vented box stiffened by the sealed chamber and with no driver contribution to the sum response) are all quite easy to add.
