Adding a ctrl-right click and drag to split current item stack evenly between buildings selected by drag boxWhat
Currently you can ctrl-right click to drop half your curent stack into a building. This is cool for spreading a resource around among a few buildings, however can lead to very uneven distributions because it uses half the stack remaining where say youre holding 100 coal and your trying to fill your burner drills, inserters and smelters. The first few get almost all the fuel and the last few get 1 or two each.My suggestion is to drag a box with ctrl-right click and it would see “hey there are 4 things within arms reach that take the current item, i got a stack of 100 so they all get 25.” Rather than the first getting 50, then 25 then 12, then 6, then back over the first so 56......
Why
Just a simple interface addition to make things smoother and more intuitive. As a side note it could extend to ctrl-left clicking as well to block pickup from a set of buildings
