(Feedback from an evaluator) Something that might be handy is to merge the category feature on the menu with Confluence built-in categories, that way any changes would be at both places. That could work so that you create categories in Confluence first and assign spaces to them. Then from your addon, you can pick a ready-made category and it will list all the spaces it contains as suboptions to that menu item. If there would be a way to also create the Conluence categories right from your addon, that would make the feature even more complete. Just brainstorming now.
