How to input precise amount of items when splitting stack

To split the precise amount of items in a stack follow these steps:

In this example, we will split 36 stones from the stack

1. Shift+Click and drag stack of items you want to split
2. Use slider to approximate amount of items (for example - between "30" and "39")
3. Click on the left number
4. Use backspace to remove the last digit
5. Enter the required amount ("6" in the example)
6. Press "Enter" (!)

We understand this is not the best way of doing it at the moment and working on improving this function usability.
