Is it possible to delete an annotation, a notification or a note ?

Annotations on Bricsys 24/7 are a great tool to comment on a specific area of the document. Notifications work in a similar way to emails and document notes look similar to sticky notes. All together they remain visible over all the revisions of a document and all of them are revision based which means that you cannot see the annotations, notifications or notes of previous revisions while viewing the latest version of the document. Also, it is not possible to delete any of them in order to keep the original track of a document that has been edited while the project runs.
