Its pretty self explanatory in the title.
In a minecraft world ive been mass dye, which as you can tell it a lot of clicking and I was wondering if there was a mod that would it all for me? It might even be as simple as a macro? but I haven't found anything.

The second part is I'm quickly filling chests and dispensers, I know theres the shift double click will send half of the inventory into the chest but I want a way to transfer it all at once? or extremely fast.
