Add way to preselect/change different market caps and volume

Would be good if there were a way (ideally in the UI, but config file would work too) for thresholds for marketcap and volume. I think it went up to $250k or something like that... would be good if you could go up to... say $1M-$5M.
Something like a drop down/capped slider would be pretty cool for both volume + market cap
