Archive Team Logs, not just Total Stats
Currently the league history just includes "End of Year Roster" and it displays each players' total stats for the year, not the actual stats scored for the fantasy team.
As a commish, I like to post actual points/stats scored for teams at the end of the year. If these were logged/archived, it would be easier to track these and for dynasty leagues, show which players have been the best for each team over the past years.
This isn't just for historical documentation, but also for strategy for dynasty teams. Just because a player was good last year, doesn't mean you actually used him to his greatest potential and maybe you can afford to trade him. Is a player declining annually? Is a player on another team being under-used and you can get a deal on a trade? Is someone trying to over-leverage a player they aren't actually using?
All this is available in-season in the Team Log. The information is already being gathered. Just asking for it to be archived for future access for those in dynasty formats.
