'Library' could display 'content' and 'folders' at the same level
My suggestion is about the 'Library'. I think that it would be really useful to have all content (Content and Folders) in one place same page. I think that the tab's menu (Content, Folders) could be removed and display all the content together.
I think it could be a great UX improvement. Is just a matter of distinguing clearly what is a folder and what is a document in the same list. The same way that google drive or any OS does.
I feel like the simplest way to move forward with this is to keep the 'Library' as it is right now but removing the tabs menu inside the 'Library' and displaying documents and folders at the same level. Here is a 'quick' mock up to help explain my points.
