This suggestion is two-fold. First, I would love to see it made possible to add the same stat to the HUD twice. I would love to see the ability to filter a stat to show only the X most recent hands, sort of in the same spot as "Adjust color of stat for sample size". What I envision is the ability to make the same stat appear twice, once as an "all hands" stat and once as a "in the last 50 hands" version. Stats get muddy and meaningless when you have thousands of hands on somebody but the player is capable of adjusting.

Second, If this is too much work because of the HEM/HUD framework coding, the ability to filter hands by recent # in the same menu as filtering by last 365 days would be a good compromise.
