CLARUS  First of all, thank God for Lostify! It's the only way I've found to tag TV Shows as TV Shows so that FrontRow recognizes them as such. (Tagging them as TV Show in iTunes simply doesn't work.)

Second, if you are tagging a large number of files Lostify requires constant user intervention and takes a *very* long time to rewrite each file to disk.

A great option for a future release would be a batch processing option. For instance, "tag everything in this folder as TV Show" and forget about all the other tags.

I'm greatful that Lostify exists at all . . . and it could be even more useful with some added functionality.
