These are fun to read 
I would love to have a freeze audio feature in Dorico ( DORICO freeze function? ). This would allow users to create larger compositions with larger sample libraries but keep the need down for insane amounts of RAM. Many DAW programs have this feature for that reason.
Even if it were just in the “Pro” version (which would make sense), it would be well worth the money since it could save a user from buying more hardware.
