Apologies if this one's been said already - I didn't see anything, but I'm new to the forums so I might have just missed it.
I've always felt that the 'Clip Position' and 'BPM Sync' parameter animation modes were one of Resolume's best features. That said, I would love to see them replaced with something that allows finer control over the parameter based on the relative position within the source. The ability to draw a curve defining the parameter value at a given position would be extremely powerful... I'm thinking something similar to Ableton Live's automation envelope:
Drawing the red lines determines the value of a parameter at a given point in the animation... Food for thought
