It might be cool if LB had a single setting with various performance levels that adjusted all the many LB/BB settings that are related to performance based on the setting chosen, but could be overwritten in individual settings afterwords. So, maybe setting "Light" could give you all settings that would improve performance as much as could possibly be set in an automatic way (yes it could mean things will look uglier!). That could be used on a slower system up to super computer. The settings could still be tweaked individually. This new setting would just let you reset them to a chosen set of settings right then and there. Maybe also the ability to save your current custom settings as name xxx as well. Seems like a fairly simple development effort that could possibly help people out a lot.
