Let teachers log in ONCE to Teacher Area

Currently, teachers have to log in with their feature password to each separate function in the teacher area. This makes it cumbersome to switch to different features. I get tired of having to type in that password so many times. Why not just allow the teacher to log in once to the teacher area and do everything without having to log in for each separate feature? I understand this is for security in case the teacher walks away from their desk while loggin in. But at least make this an option. I'm in a computer lab and don't have much risk of students seeing or using my computer.
