For what you want 3 symbols? What if simply hower mouse to get popup - player name is there.
Seating Preferences is not always reliable especially when you have just sat down (and sites like PKR are terrible for it) not everyone uses 'hover for popups' some people use click. I can't afford the time to click a popup then close it just to make sure the player stats are for who I thought they were.
Space everyone loves more space 3 is better than 6 in that regard.
It seems I'm not the only one either.
Yes, definite option for only 3 characters in abbv. name. A option to have 2 or 3 would even be better.
As previous poster wrote, space is important and for certain sites we need the names.
HM1 had the option for 3 char. abbv. name!!!!!! That is important to me.
Instead of setting fixed limits like 3 or 6, why not replace the "Decimals" dropdown on this stat with an integer edit box that accepts any integer value? Then people can tune it to exactly what they want? It would be no more work, as I'm sure you're just getting a substring now of the hardcoded lengths. Instead you'd just substring the first X characters as specified by the user. This is one of those easy changes that gives the user the most control without any extra work on your part, and goes a long way towards improving the flexibility and user-friendliness of the product.
