Sugar Regular user has access to Developer tools!!??

I recently found that my Sugar instance only has two Types of User now: "Administrator" and "Regular User"

I believe there used to be a "Developer" Type at some point.

Much to my dismay I found that "Regular User" has access to Studio, albeit restricted to Document Template module, and FULL access to Dropdown Editor, which is scary! Scream

So my question is two fold: 

  • is this standard behavior?
  • how do I completely remove Admin menu access from Regular user?

Thanks,
