As it seems to be no way to configure sections in blueprint, there should be a “no section” button in the section panel (in the detail panel) that should show all categories without sections.
So we can see only the categories that we created.
This would furthermore help with the infamous category order system.
And a greatest feature will be to add in the blueprint class settings the possibility to add and configure sections:
- An array of customs sections that each one can list an array of customs category names.
