Rated 2 out of 5 stars
Good idea, but...
1. balky - too much fiddling to get it activated (need to sign-in each usage and use hotkeys each page refresh - a deal breaker for sites like Rotoworld where you're constantly moving from one player update page to the next)
2. intrusive - the info is good, but the icons are too big; they break up the flow of reading.
3. not very "smart" - when articles continue to use just the player's last name, as articles commonly do, this app can't identify the article's focus player.
