Let get an Improved Elevator. The ones we got are painfully slow!
Theres gotta be a downside, nothing can be perfect, be thankful for the ones we got having a magical call/activate button and ropes doesnt needing thralls to pull in.
I would like to be able to use an elevator for multiple floors like in real life, instead of a one-way function.
Great idea! Putting a taskmaster in an elevator would make them faster!
Let us expand on this idea an make several thrall slots so the more T4’s you put in the faster it goes, so you could adjust the speed 
But I would like to see all Thralls to be able to be placed, needing a Taskmaster to instruct them
