[FEATURE] Adds checkbox 'Can change editing mode'
Adds checkbox to backend user settings which allows to non-admin users to switch between editing modes.
It would be nice that I can hide this check box if edited user is admin. Is it possible?
Yes you can Damjan.
Assign the bool of this to the fluid view and then you can decide to hide or show the checkbox.
You can maybe hide that with a displayCondition. http://docs.typo3.org/typo3cms/TCAReference/Reference/Columns/Index.html#displaycond
