It is important to let users decide their default dialog size. Some have ultrawide monitors and this module does more harm than benefit.
Here I add such task to roadmap, to avoid forgetting about it.

This addon had 2 problems after migrating to v11:
1. One call to backend's `ir.config_parameter.get_param` was done for
each instantiated dialog, while the setting served for the whole
session equally.
2. That model is now readable only by admin users, so non-admins
couldn't use the default at all.
Fixed now.
