o Intensity readers should be constrained on the x-axis when in side-view. o Real-time model won't work when paused (wavelength comes out wrong). o Add vector view to photon view. o Add full field to photon-view? This would require a major rewrite of the model (which is now 2-d and nonvectorial). Is this really what we want here? o Should we show intensity readouts anywhere, or just wave values? o How to control frequency/amplitude when there are two wave sources? o We could get rid of edge effects by maintining a higher lattice than is shown on the screen. o Add correct units to measuring tape. o Add correct units to stopwatch. o Make it so "pause" then "step" uses a sensible dt (not the actual system delay) o Wave area size should depend on window size.
