2) What type of code customization? Maybe if you point me in the right direction (file, line) I could manage to edit the code to disable those block sign.
3) I know that, in fact I did install a role editor plug in, the problem here is not to create roles, but to assign them in bulk to all of the packages. Above you mentioned “no such ready way there, but we can help you there”, how can you help me?
Thanks again.
