to-do: walls should show/hide on bounds type change wiggle me power ^2 in readout "velocity" and "accel" text in play area are backwards when x-axis is reversed sim should stop when time reaches max? >>when hitting clear, data continues to appear on graphs, but it's not recorded sim should come up paused and start when the user does something? Rotation starts in action, but main site version of moving man waits for user first recorded time is not 0.0, but dt highlight to indicate active variable? vectors control should use flow layout, not horizontal in-chart readouts should have correct text clear button broken? (after using expression evaluator) record/playback crash sounds? during crash, velocity and acceleration curves look awkward (step back in time) need to throw away data when not recording (as done in rotation sim) done: crash into walls/bounds playback panel vectors for display sound time readout graph tickmarks: in-graph, bigger font walls/free range option expression evaluator reverse x-axis man should change direction graph x-axis should be time (not ticks) when zooming in/out, data disappears
