Kdenlive itself is not using threads. But MLT now supports multi-threading 
(using FFmpeg threads)... that's all I can say about that.

Well, I have one device (a CAVS SpaceShuttle), and if the permissions are set 
up correctly (you need read access on it), you can seek in timeline and play / 
pause with it. The configuration options in Kdenlive could also be much 
improved to make it really useful. I have no other reports about similar 
devices, so I guess it's better to say it is still an "initial support

Some of the video effects are listed on the kdenlive web site: 

A few frei0r effects were blacklisted because they were duplicates of MLT core 
effects. Only one is completely disabled because of a crash. 
In my Kdenlive install, I have about 35 video effects and 19 audio effects

I have 30 transitions listed, but I think only about 10 of them are usable 
(the other one - taken from frei0r - would need some extra work on MLT and 
Kdenlive to be usable)

If some people want to help coding, the best is to have a look at our roadmap:

They can pick up a feature or bug and try to work on it. Questions on the code 
can always be sent to this list.
