Here's an angle no DAW vendor has thought of: reporting.
The kind of software I make my living with might seem far removed from DAWs and other audio tools, but there are more similarities than one might assume. It's all about turning numbers into something real, data into information, be it in the form of sales projections or music. In my world, reports are a big part of that process.
Here's one example: project reports and track sheets. In the days of tape recorders, what did you find affixed to every reel in the vault? A piece of paper (or multiple papers) showing track listings, run times, routing information, effect settings, microphones used, recording dates and times, artist and engineers' names, and other project notes. In the digital world, even more information could be included, such as virtual instruments and elapsed time spent. Some of that information is currently available from SONAR, but not as a nicely formatted report.
Another report users might find useful: virtual instrument listings. These could be for an individual project, a group of related projects, or global to the system. Wouldn't it be great to have a list of every project on disk with a list of which virtual instruments and which patches/libraries were used in each? Somebody hears an old mix of yours and says "I want THAT bass on my record" - no need to rely on memory alone to find out exactly how you got that bass sound eight years ago. If you had a searchable database, it would be trivial to locate which instruments you used for what project, or what your most-used instruments were, or which instruments you've never used.
Here's another: routing matrices. Got a warning about a silent bus, but can't figure out why? Got an instance of Kontakt that won't freeze (just happened to me last week)? Getting confused with multiple headphone mixes? Can't figure out why your exported audio sounds different from the project playback? These kinds of questions could be answered in seconds with a graphical routing map. Reports needn't to be on paper.
