i was just going to ask this ... could you explain the pros and cons of having a single repo for the issues or have the issues for each repo? (sorry not a long-time github user here 
)
for what I understand, If we use a single repo, we must use additional labels and leave the issues "disconnected" from its repo. What happens then with the PR?
do you have some examples of projects using this solution?
if we decide to use the classical approach (each repo has their own issues) we can use the search functions of github to see the issue of the entire organization ... or could we try zenhub? It seems free for open source project and it support multi repo
for the rest I agree with @stephdl
@giacomo I apologize right now but I will do other tests with testdev1.. sorry for the email
