Joe and Elpidio,
I feel that the name Balls and Rows in Column Filter would be easy to remember and also undertanding the filter's function would be easier. The word "Balls" would be a good replacement for "numbers drawn" (actually the balls are drawn, and numbers are on the balls). And we try to select the numbers which will be drawn.
Elpidio's idea of new filter is good.
However, talking about columns within a column would be inconvenient and confusing. I would use the concept of VERTICAL GROUPS within History Differences tab. for a given column.
Numbers in rows are arranged horizontally in the ascending order from the left to right. It could be an advantage, because there would be a concentration of HIGH NUMBERS in the rightmost vertical groups, which should be left at HIGH POSITIONS (the 4th, 5th and 6th position in 6/xx game) but removed from LOW POSITIONS (the 1st, 2nd and 3rd) in the process of filtering.
In the leftmost vertical groups most commonly there would be a mixture of Low and High numbers and filtering would be more difficult and probably less effective. But a similar situation occurs when you use the existing Positions Range in in Columns filter; in the first several rows you find a mixture of Low and High numbers and such rows with its numbers cannot be filtered out (unless you want to take risk).
In my game, which uses 45 numbers, probably 15 vertical groups would be enough. For games with more numbers, 20 groups might be needed.
I suggest the name Balls & Vertical Groups in Column Filter (unless there is a better name).
I expect that both filters, when used together, would provide a useful and attractive combination of filtering power.
Best Regards
Jerzy
