Allow using backend for registered users

[Zeka]

Hi. 
PW is great tool and it allows to build nice front-end user areas with rich functionality, but sometimes it takes too much time.
I have been thinking about is it safe to allow for some group of registered users use backend to manage their pages and content. If I am not mistaken, Cms critic went with this scenario. Especially with the new UIkit based admin theme we are able to easely customize how backand looks.
But is there some specific cases or areas from the security point where I need to put more attention to?

The PW Backend is basically a highly-specialized frontend to your data, so if you set your permissions correctly you can let whoever you want have access to it.
