AURELIUS Pricey for an average small non profit theater company... Also a little buggy running Intel 10.4.11. (e.g. launching from show file quits application). However, developer was extremely helpful and responsive to questions, and followed up. Otherwise, nice interface, very intuitive, easy to use. Hoping for a later stable version. (Version 1.1b9)
