Befroe you say "search it!" i already did it.
I got in the Nether a Pump station for Lava and its going to BC tanks.
So why not making be able to refill cells with lava with rightclicking the tanks?
This would be helpful and not if i get lava at coast of lava i get burned/pigzombies push me in/Ghast attack me and i get burned.
This would be very Helpful.
And the secound thing is: Elevators.
To build them you need a type of electrical vertical Railtrack/ Sensor buttons to request Elevator to your Position and a Control pad.
Simply just build the Elevator frame/content then let it be insta-frame with the Control pad. You can say how big it should be with x/y/z size and x/y/z offset to say: "This Cube is the Elevator!"
Only the Rails must be energized and not the control pad so it it easier to make it.
If you place Luminators in it it will auto-take energy from the energized rail track. (and not MFE/MFSU/MACHINES, because this would be op)
You should be able to say the y coordinates where each elevator stops or horizentally x or z.
This would be very helpful for mines/Laboratories/high building and more.
So that you dont need expensive teleporters to get quickly up/down.
P.S.: Sorry for bad english, because im german.
