I'm running FireFox 42.0 on Ubuntu 14.04LTS, and I have a few comments about the upgrade.
I prefer the BETA lineup right now over the existing one. However, if my player is the 'last' player listed on the bench, or the last player in the rest section, when I try to swap them with another player, the options are not displayed. The box that appears with the lineup position (1,2,3,etc) does not extend below the 'Bench' or 'Rest' sections, so I have to go to the 'non-Beta' lineup to make the change.
I'm not really sure why there is a need for the separate 'Rest' section. Can we not just have a 'Bench' and have the players position of 'R' like before? This seems to cause a lot of unnecessary jumping around and scrolling when changing a players status.
And the lineups/pitching staff in general, do we need the players photo there? Can it be optional? I used to be able to fix all 15 players on a screen making it easy to see stats/ratings for lineup changes, now I'm constantly scrolling because I can only see about 12 guys on the screen because the rows are taller to allow for the player photo, seems unnecessary. And when you do make a change everything jumps around immediately. Seemed much easier to me before the change.
If you look at the Hall of Fame voting screen, I can see all 30 players eligible, and their stats, with no scrolling at all. it's great to compare the HoF stats. Not sure why the lineup page couldn't be as concise.
