I agree that would be helpful for many pieces.  Right now it is up to the composer to decide what text to include in the More Info section.   The upload process to the current showcase is quite clumsy.  It will not be hard to have someone write us a program that will include promps for specific information.  It will make the process as simple as answering a series of questions i.e. Title? __________  Voicing?________ Accompaniment?________ etc.  I believe that time will come but it is not yet.  When the time does come I will be asking for suggestions of what we feel is required information.  Thanks for giving this some thought, I hear you.
