I never would have thought of this issue, so thank god for @OttoneuTrades and his insanely in-depth auction strategy.
I have made some changes to search results and the wish list that result in the player name taking up much less space. This should reduce horizontal scrolling on free agents by a lot.
There will still be some situations in which horizontal scrolling will be required unless you have the largest of displays (which is my response to some of the other issues up thread as well), but the feedback in this thread has helped me clean up the interface even more over where it was a couple of days ago.
Thanks for everyone's feedback so far, and please keep your notes coming if you have something no one else has mentioned yet.
