Currently, the logs shown are the best damage for tanks/dps and best healing for healers.
Being able to change what logs are being checked based on class and spec would improve the clearness of players playing more than one spec (or if a player rerolls spec).
For instance, a restoration druid with boomy offspec (or rerolls boomy) with good damage parses as restoration, will show damage parses as restoration even if the specialization is boomy.
Issue example
Restoration damage 
Balance damage
