I would like to have a possibility to reduce size of the panorama (keeping the ratio) lets say from 100MPix to 5 and send small panoramas to somebody who can create a tour and send me back KPT file. I will then launch it and open 100Mpix images, compile and publish. It will save me plenty of time because I will have to send "only" 1-2GB of data, not 40. I made a test with 20 and 4 Mpix images and sadly it didnt work. Opening 20 MPix images made the output as it was 4.
I hope that this feature can be usefull to others.
