As a published classical composer, computer scientist, and an early and longtime (over 20 years) Sibelius user from version 1 to my present version 5, I have found the floating input note and symbol keypad indispensable - will the new Dorico product at least have an option for utilizing floating sub-Windows screens for inputting notation ? I very much look forward to such an option, as I have always found the Sibelius interface comfortable. Also, Congratulations on the completion of your project - as a programmer I appreciate the effort involved in such creative endeavors.
