I love the program and it's working great with my Canon 7D HD files using the proxy back round.
Color grading... I would love to get an easy quick way to do color grading similar to Magic Bullet....I know thats a lot to ask but everything else is there.
De-shaker...even on a dolly I get bumps sometimes and a de-shaker plug-in would allow that footage to be used.
Correct slow motion...the slow motion in Kdenlive rebuilds the footage somehow and makes it look weird. here's an example between Avidemux and Kdenlive so you can see what it should look like. Avidemux take my 60p footage and when I drop it to a frame rate of 24p it plays smooooooth:)
