Smewt 0.3 has just been released!
This is an incremental release, that is, it doesn't add any new fantastic features, however it has seen a lot of polish everywhere.
Among others, Smewt should guess what your files are with a much higher chance of success and the subtitle downloading now works for both movies and episodes!
There are also lots of tiny annoyances that have been fixed, and in general Smewt should give you a much better experience out of the box.
Hope you like it!
