1) First of all I would like to propose split the Technical Writer vs Customise Design permissions. It's totally different working skills for articles creation and working with HTML/CSS/JS Design. It creates big problems and security issues to give customise design option for technical articles writer.
2) Availability to edit sections by agent groups (not all agents).
3) Guide permissions per brand! Different content managers working on different product, so should be normal restrict agent for brand.
When you working widely with Guide, few brands and many agents has the same permissions it can create big incidents.
We definitely and really need these options in the Guide Manager permissions.
