Its nice to see new features

The TV Sorting seems nice, but doesn't do what I hoped it would do, well.. That's not really true but here's what I'd like:
My TV shows are mostly .mkv files (I don't see those mentioned in the "%ext" variable. Do they work?
I store my shows at
Drive:/Series/%showname%/Season %season%/%filename%.%ext%
For this I normally use a tool I've created to move them to this specified folders.
What I'm missing in the SABnzbd TV Sorting is an option to maintain the original filename. I don't want to rename the files to "S01E12 - Episodename" or similar. I just want to keep the original filename, but move the show to the specified path.
Additionally, I'd love to see a "add to playlist" option so it writes to a specified .m3u file. Should be easy do-able, if my Python wasn't that rusty I would've added the feature myself.
M3U files are rather easy, first line is "#EXTM3U" and every line following is just a path+filename to the specified episode.
