There are been several topics already started and closed on improving stack manipulation. Please search the forum for the keyword, “stack”, to review the previous threads.
So the stack saga continues…
I propose the idea that the computer should do what it does best and have it calculate separating stacked items based on user input. Possibly the simplest way to implement would be to add functionality to the existing window that pops up. Allow the input line to accept fraction values such as 1/4, 1/3, 1/2, 2/3, & 3/4. Or any other fraction.
Also, taking from one of the previous ideas already posted. Make it possible to select multiple stacks for splitting either with a specified number or a fraction as indicated above.
