 things to try:
 
+* fix status bar to show elapsed time, per-iter time, per-pixel iter count
+
+* 'turbo' mode disabling graphics in full or part
+
 * patch the entire expanded-ram imul8xe on top of imul8 to avoid the 3-cycle thunk penalty :D
 
+* maybe clean up the load/layout of the big mul table
+
+* consider alternate lookup tables in the top 16KB under ROM
+
 * y-axis mirror optimization
 
 * extract viewport for display & re-input via keyboard
