Hey SS dev team. Love the platform and your efforts to keep it simple and accessible! I understand your desire to keep the main nav a simple as possible so that it continues to be s efficient as possible, but I think direct access to the Tag Manager and Custom Fields would be an excellent addition to the main navigation.
Sure the the links to the tag and custom field manager are handy in their current locations, but it would save time and clicks if they were also linked up in the primary nav. Sometimes I just want to make an adjustment to a tag or to a custom field without changing a form or whatever a tag might be associated with, but to access them I have to go through another component instead of having a direct link.
Keep up the great work!
