Congratulations go to Tian, with his work on GCstar, which hit version 1.0.0 this past weekend. He's added music collection management, to go along with books, movies, and video games.
I'll admit, I get a few crashes when I try it. Mostly associated with errors like
Magic number checking on storable file failed at lib/Storable.pm (autosplit into lib/auto/Storable/fd_retrieve.al) line 349, <RCOMMAND> line 1, at /usr/local/bin/../lib/gcstar/GCPlugins.pm line 88
but it's a very capable application, with many more search sources than Tellico. Heck, you can even use all of GCstar's data sources in Tellico.
