It would be nice to have a "mass" servo activate/deactivate.
Every time I want to create a new sequence, the system defaults to all servos on and I have 17 of them to deal with. Since I'm doing sequences in small groups (eg arms, legs, one side, other side, etc) I have to enable or disable many of the servos at once.
In the servo check field, at the top of the column should be a "servos all off" and "servos all on" check box. If you only want one servo on, from the gui you would check all off, then activate only the servo you want.
