This may be a little off-topic............ Regarding the MEMO feature, it sure would be nice if the usable writing area was box-outlined. Usable is about 80% of the total indicated space so you can run out of it easily. And as long as I'm streatching the topic, could you make the 720 save the MEMO settings like COLOR and STROKE on power-down? As it is now all the settings are lost then. And just one more......... How about a toggle feature between NAV and MEMO? I use MEMO to record ATC instructions and it would be sweet to switch between these two modes instantly.
