Unified Annotation Versioning #7839
Description
Currently, an annotation can have multiple "tracings" (skeleton, volume, editable mapping). All of these have an isolated version history. The UI also exposes these separately, which can be very confusing to deal with from a user perspective. While we could adapt the UI so that only one virtual version history is presented, it might make sense to change the underlying structures. We should draft a design doc and discuss how to proceed.
