I subscribe this comment, non-linear interpolation using curves would be extremely useful. Another obvious thing I often miss is the ability to change the length (duration) of static image clips in the project bin (currently? - haven't tried the latest version yet - the only way is to set a length in the settings before importing). It seems like it doesn't matter at first, since it's a static image, but start adding effects and keyframes and any resizing done in the timeline can mess everything up.
