Would it be possible to look into the possibility of choosing when annotations are visible?
I use the visibility track of my models quite a lot in my models and need to add annotations to the parts in my animations. However when certain parts are invisible the annotation is still present but just floating in mid air.
See the model below. Annotations 9 & 10 for example are on parts that are not visible in the first animation so it would be good to be able to turn these off until they are relevant.
