Following feedback, I've changed the functionality on the points pages slightly. You can still add teams together to compare performance of players from just a few teams, however, clicking on the team button again will remove that team from the selection. So, if you've been looking at Tottenham players and now want to examine Blackburn on their own, just click on 'Tot' followed by 'Blk' (or vice versa). To aid recognition the selected team buttons are coloured blue.

The same change applies to cricket and football points.
