This is still a Work In Progress, the below screenshot shows the design I had in mind.
I assumed that the button on the left allows to open an internal issue form (with only summary field) or eventually annotate in case some issue exist with the same summary (this is handled by the backend automatically).
If the number of occurrences > 3, the usual button to open an bug in bugzilla is enabled at the right of the internal issue suggestion.
@Archaeopteryx if you have any suggestion, or idea about this it would help me going on with the implementation.
