How many times have you been asked to borrow your PC for 5 minutes?

And how many times have you been rejected because you have sensible information on it/ did not trust that person entirely/ Screen locked after 10 min and you didn't want to tell your password by phone ?

My idea is to create a guest session mode

What is session mode?
+ Very quick and easy switch between regular and guest modes
+ Very limited activity
+ Very limited list of programs user is allowed to use

When session mode?
+ Activate by plasmoid
+ "Guest mode" button near logout/ change user button
+ When screen is locked "Guest mode" button near change user button
+ In KDM
