What would you want next in a free investing research terminal?

We launch on Tuesday. The free Research Terminal already covers 30 markets (return, Sharpe ratio and worst fall side by side), a portfolio crash test back to 1972 and a 4% rule test since 1872.

Before launch day I'd love to hear from you: which market, tool or chart would make this genuinely useful for your own investing? Any idea is welcome, small or big.
