Hello fellow hoarders,
I've been fighting with a big collection of video files, which do not have any uniform default track selection, and I was sick of always changing tracks in the beginning of a movie or episode. Updating them manually was never an option. So I developed a tool changing default audio and subtitle tracks of matroska (.mkv) files. It uses mkvpropedit to only change the metadata of the files, which does not require rewriting the whole file.
I recently released version 4, making some improvements under the hood. It now ships with a windows installer, debian package and portable archives.

release v4
I hope you guys can save some time with it :)
