Collaborator interface for extensions
Although extensions can perform active and passive scans, AFAIK they have no access to collaborator, thus cannot verify out-of-band interaction. Am I mistaken? If no, it would be a great thing to have.
That is correct. Within the coming year, we are planning to provide some manual testing tools that make use of the Collaborator function, and at that time we will also look at exposing the same capabilities via the API.
