Quoted from phishrace:
Should be adjustments in Feature Settings, although it sounds like the adjustments may not be working (software issue). If you turn it down to minimum and don't notice any change, it's likely a software issue. Changing the settings should be noticeable.
That dictates the amount its used not the strength of the effect. I like shakers but even on STLE would rather have it weaker. I'm going to try some things today, post results later.
