To close debate you still need a 2/3rds majority to concur. If she does her homework she can probably out fox most of the adults on the board who are used to doing things their own way. For example any motion to end debate has to be voted on and pass by 2/3rds majority. If she has the floor of course she can call a point of order, you can motion to end debate unless you have the floor.
"If more than one motion is pending, the motion to close
debate should specify the pending motions to which it applies.
For example, suppose a main motion, an amendment, and an
amendment to that amendment are all pending. If the proposer
of the motion to close debate wishes it to apply to both the
amendment and the secondary amendment, but not to the main
motion, this qualification should be stated. If the motion is to
apply to all pending motions, this should be stated. If the motion
to close debate on all pending motions is adopted, an immediate
vote must be taken on the amendment to the amendment, then
on the amendment, and then on the main motion. The motion
to close debate may be applied only to successive pending motions
and must include the immediately pending motion.

So I don't see how this procedural rule soured you so much.
