Dear Triarius,
The operation of adding and removing folders is not something you do very often. More over, you are usually protecting data which is important to you. So it is better to do things step by step, and check if all is fine before moving on next folder. So while convenient, it might lead to bigger problems this is why I doubt this will be implemented.
Regarding unlocking all folders, if you mark the folder to unlock on logon, then it will, well

, unlock at logon. If you mark all your folders this way, they will all unlock when you log on (and lock when you log out).
This might be something you like.
I hope this helped a bit.
Cheers
Zsolt
