There are no hosts in the trusted list, even after granting control. Maybe I am missing something?
Also:
Maybe change this:
"To add them, you have to share your Mac, then peer it on other one."
To:
"To add them, you have to share your Mac, then control it on another one."
And maybe change:
"To avoid behind controlled by other Mac, just go to the trusted hosts edition sheet, and delete it."
To:
"To avoid being controlled by another Mac, just go to the trusted hosts pane, and delete it."
