I like to keep a tiers-based spreadsheet which I have adapted from Rookies' Median Draft Report. I will also keep J35J's spreadsheet open which has also been adapted to fit my league and my tiers. The 90 seconds can go by fast sometimes especially when other teams do not take their entire time. Planning ahead is key, IMO, and I like to stack guys in my queue especially in the later rounds.
Someone else mentioned paying attention to the preferences of your league mates and while you won't catch everything, I do this as well. We have a few homers in our league that you can count on like clock work to reach for certain players and there is also one guy who always starts to load up on rookies near the 10th round. Last year, between picks 10 and 19 he took, in order:
Longoria (I was stoked when he dropped him two weeks into the season because he was in AAA)
He's the reason why I may not get Wieters in my league but if history repeats itself and Wieters starts the season in AAA....
