Im not well versed in C++, so I cant exactly sit and code just yet a plugin that would extend the capabilities of the tagscript we have now, but I wish to be able to at one point. Though scross referancing files may be a bit of a slowdown, the database search seems pretty fast, and if there were a way to launch a search and effect each search result as per the tagz command, that would work. Such as, if playing, find in playlist tracks with same album, then execute whatever on all of them. Id personaly like to see that included in the masstagger, so that i dont have to manualy autotrack all my files

Another thing, while im on it, that I would love to see extended in terms of tagz' capabilities, would be the ability to define our own functions. There are certain scripts ive written that I particularly like, but unfortunatly I cant pass more than one argument into them. That, in itself, would open up a few new possibilities for me that i would enjoy.
