I don't believe anyone at LiveCode centre would admit or suggest that any of those would be because they chose to assume that users didn't need to be told.
This is a universal problem that affects you, me and everyone else who has ever written an essay or a set of instructions:
the assumption that the reader(s) know something when they may not, versus the temptation to write instructions
that are so over-loaded with stuff for someone who knows exactly nothing that they are unuseable.
Just the other day someone had a problem with a Windows 10 installation and asked me to help.
Over the phone they mentioned, "You know XXX, YYY and ZZZ are not working." and were brought up short when
I told them I had NEVER used Windows 10 and did not understand what they were talking about, and were they
to let me see their machine I might manage to work out what was going on.
