You really need a better interface than the + and - signs. That is a lot of clicking to get into the 5000 plus range. I am trying to automate the Thermalillies from Botania. Releasing enough lava for 7 Lillys. then closing a piston over the lava drop area until the plants cooldown has expired. Rinse and repeat.

This suggestion would also be appropriate for the Advanced Redstone Torch.

Not sure whether you knew but shift already increased the amount by which it changed.

With this it's:

Shift: 10
Ctrl: 100
Both: 1000

The Advanced Redstone Torch only goes from 0-15 and already has the shift functionality so i don't think more is necessary there.
