It would be useful to have a token which is the flow and project timing in hours:minutes:seconds, calculated from the tempo track. For concert music such information is used for building the program, and for games it would be very handy while composing and for project planning the stems. I image the film composers would find it useful too. Of course it won’t necessarily be 100% precise but that’s not needed at any rate.
For example my score information page would give the total timing, and on each flow I’d have a field to show the timing up near the first page title. As it is I need to calculate that all by hand, and I use it while composing to know how many minutes of music have been written.
