Perhaps the last bigger update of this season is here. It includes a couple of enhancements that might help even at this point and a lot of fixes.

Marked players price calculator to calculate even complex trades
Lineups highlight players from current roster

Trade calculation appears above marked players:
-mark players you want to sell and buy
-display marked players through roster or players view
-click calculator icon to the left of player price
-click again to subtract price, click third time to ignore

Larger bug fixes:
Season/round context is respected within all? views
Season is not stored into session anymore - you will have to change it manually from actual season after login - caused troubles Playoff league history fixed
