What I think would be great for dedicated servers but expecially for role play servers is to be able to enable shifts
A-Shift B-Shift and even more if you like.
Also being able to lock certain positions within a shift, allowing server owner to always be on A-shift for example.
In servers it would add to the roleplay of having a "night shift" allow you to just relax aboard the ship when off-duty. You could just always select a basic role until your actual shift comes around again.
Allow a shorter shift to train bridge officers with supervision.
In server options you could have options like.
Enable Crew Shifts yes/no
Set amount of shifts _
Enable Training shift yes/no
Set in game time for shift to start
A-Shift ____
B-Shift ____
Bridge training shift ____
