In a kitchen, if you pull out a drawer, and at
some point it won't come out any longer because
of some small built-in brake flaps or whatever
to prevent it from falling down on the floor if
pulled too far - and all this works, so it
stops in good order - is this a) an error,
b) something that needs to be communicated
explicitly to the kitchen operator, or
c) something else?

IMO the echo area is far too chatty and only
writing this I noticed several messages that
are of no value to me.

To take another example than those mentioned:
"Auto-saving...done" and "Mark set". In what
way(s) do I benefit from seeing them?
