More ideas for the wish list if you get bored.
#1 It is in alphabetical order in Tools -> Groups but it would also be much easier if it were in alphabetical order within Tools->Toplists (all areas) and for the New Trades display (on trade.php) as well to make life a little easier. It's not a problem with less than a dozen toplists but I have a site with over a hundred toplists and it gets crazy keeping track of them all when they are scattered.
#2 I believe another script offers "Group weights" or some sort of implementation like this - it might be a great idea within TP too. So that say I might include a site 100% in one group but only 50% in another group. What would then happen is in the 100% group it would get it's full point/uniques/etc values but in the 50% group it would only get 50% of those values. This way I can more effectively put a site in different groups with more flexibility.
