One thing I'd like to be added, is a timescale limiter.
When I watch US2 videos, the new users would drag the timescale slider all the way to the right, so the sims speed increases to the point where the Sol system's (the name of our solar system) planets start flying away from Sol, (the suns name) and I find it a bit annoying for these new users to make false conclusions based on their error.
I'd like their be a limiter to prevent this, and a notification telling new users that increasing the timescale would decrease the sims accuracy.
