Is it possible to have little arrows at the headers for multiple sort/filter options?  I'm thinking the kind of functionality that Microsoft Excel has, but applicable to the My Game page.  It would be great to be able to sort more than one column at a time and put in criteria such as ascending or descending.

Could you give me an example of how you would like this to work?  I understand what you want from Excel, I just don't understand how you want it applied here.  I'm not agreeing or disagreeing, I just don't fully understand the application of it.  I'll hang up and listen for my answer.

P.S.  I love the informative pictogram that is supplied by the above user

An example would be the criteria I was using to select people to invite to a 1 v 1 Wargear Warfare tournament, I want to find those with the highest rating, who played more than 100 games, and had a 50% or higher win ratio.  This would be possible with Excel style filters.
