"I believe PG Music should really focus on fixing existing issues than developing new features for the software."

I disagree. MTP Library is a vivid example of a new power feature that by itself "fixed" whole truckload of separate existing issues and workflow gaps. This is one of the best tools rolled out from the time I have started using BIAB.

Perhaps "new" features could be re-imagined / re-written older features that have existing issues or limitations.
