Thank you for your reply Shaggy, the "three dots" thingy is grey and not easy to spot but now is obvious. I agree with your attitude to useability and the "power user" crowd who seem to think that everyone, like them, has the time to go into the most intimate details, contained in software manuals, of obscure software functions that 90% of users will never need.
As for the GNS 430, I'm not instrument rated, what I want to know about is that devices functionality as it pertains to VFR flight, not the finer points of coupled approaches. In the military our instructional priorities were summed up by grouping things into "must know", "should know" and "could know" categories and I wish all software developers did the same as you seem to be.
