In the decision-making phase for choosing a content management system, one often hears about TYPO3 that the backend is not intuitive and much too overloaded for the editor. That there are too many options and fields that you would not use when creating content and lead to the editors being overwhelmed.
I have also seen many backends in which the backend was not adapted for the editors or even no user groups with corresponding roles were used. And thus all users with administration rights were on the go in the backend.
In my opinion, this has to do with the steep learning curve of TYPO3, which puts obstacles in the way of beginners. But once you understand the concept of configuring TYPO3, all doors are open to making the backend as simple as possible. And only with the fields and options that you need to create content.
There is a fairly simple way to achieve this: hiding fields using TCEFORM, setting default values for fields with TCAdefault and consistently using user groups. Admins are really just admins and not to be used for creating content. With a properly set up TYPO3, you should never have to log in with an administrator account. ;-)
