Lock a folder from being deleted

Hello,
I want to have an option the prevent certain folders from being accidentally delete by choosing a lock button 🔒 to lock folder, as other softwares have.
2. The 3 dots button on the right upper screen has option to delete the folder EVEN without me marking and choosing one of the sub-folder or a file.
That a very scary option SO please remove IT!
3. Even more annoying - The button to change the view of a folder & files inside is A GLOBAL BUTTON so it will change view for all the dropbox files & folders, WHILE all I NEED is to change the view of the folder I’m in only.
I let know the support about the this few times before, but nothing changed.

Please make a repair 🙏🏻 and modify to the interface so we’ll have a better experience and use in our Dropbox.

Thanks, and waiting for your reply.
Elado.
