Is there any chance you can consider adding the ability to WARP STABILIZE to support keyframes, so you can turn up or down the levels of stabilize (or even style) on a clip.
 
The technical use case is where clip could just needs different parameters but you want/need it to not be frame aligned between the transition of the strength of warp stabilize.
 
Creative use case, basically if you have an already shaky shot, and just want a frame aligned transition where the stabilize comes in, and stops (eased in and out) to show for example a situation where the action needs to be calmed down.
 
Just some ideas,  I have been fusing with warp stabilize to try and get to know it better, and felt this could be something worth while having as I was experimenting with settings.
