Indeed it should be "name" throughout. I think that needing to copy the name/title is a rare use-case, so it's more convenient to click anywhere on the row and have the value copied. Number 3 is indeed a bug, already fixed for the next release.
Make Custom Fields less obtrusive
Ability to autotype the Value field on a row in the table of custom fields of an entry
Will be in next release, in the form of '\v{name}' wher 'name' is the name of the field. For example, if the name is 'PIN' and the value is '4321', the '\v{PIN}' will result in '4321' being autotyped.
I agree that it's a distraction if never used. Perhaps a "folding" button to hide/show this will be added in a future release.
