thanks for the update. As for the possible topics, I gave my two cents below:
Integration with Zoom and Alfresco;
isn’t there video chat already implemented by you at cern? Alfresco sounds interesting, but haven’t gotten in touch with it. Maybe the author can share his use case?
VAT logic + invoices;
especially possibility for storing a vat rate is key for any commercial conference and something not easily done with a plugin. As for the invoices, I think this can be handled in a plugin. Might be a thing on top of vat logic. This was my proposal
Translation testbed + environment;
can’t this be done in a proper development environment already? Maybe I am thinking too easy here
Extending user attributes + per-role menus;
interesting aspect, but needs to be specified.
Improvements in registration import/export
Definitely worth doing / completing
Finishing up badge field placeholder PR;
Human Rights ( not sure what this one means exactly ).
