Some wishes for the animator window

Hello there!

Its my first post here and not sure if this is the place to write my "wishes", but here we go.

Two of features that I would wish for in the Animation window:

• to visually disable an animation, but not remove it; for example - finished working on a animation of a branch of a tree, but now want to animate a leaf at the end of it. If i could "disable" the branch to move, just to animate the leaf
• to select a object in the timeline and covert curves to constants on every frame (for emulating 12f/s animation for example)

If there is already a way, please tell =)

Cheers,
