+
+wow, once I get to around 200 notes, my disk goes crazy!!! what's going on there? and then this script dies...
+
+100 notes: 3.27, ~3s, 0.015
+200 notes: 4.71, ~4s, 0.029
+400 notes: died!!!   the disk issue...
+
+once 800 notes were loaded, startup time was about 6 seconds still.
+
+
+with both @800, deleting notes is REALLY slow...
