Teachers: What mods/plugins would help you teach easier?

[mcShadesz]

Hey!

I asked a similar question on the build discussion board, but have a different slant here... For you teachers... what game features would make teaching easier for you?

Also, Students: what would help you learn better?

I have plenty of time to gather ideas so please post in the future if you suddenly get an idea. Thanks in advance.

maybe something that converts binary to decimal and vice versa? Would be very helpful.
