It’s a bit rudimentary to only show the current place in the hierarchy
and the parent. You lose a sense of how deep you are.
But we can’t just show the full path, because it can be arbitrarily
long. So what this commit does is show the full path, but truncates the
display of any items. Further-up than the current folder or its parent.
This also helps disambiguate between folders and templates, because
folders are always shown with the folder icon.
This probably won’t affect many teams, because we don’t anticipate a lot
of deep nesting.
We already have a pattern for navigation folders and searching for
templates – let’s use it for the copy page too. And I reckon we can
represent services as folders if the user has multiple services they
could copy a template from.
After showing this to a few people the consensus seems to be that
‘Templates’ isn’t itself a folder. Therefore it shouldn’t have a folder
icon.
This has the advantage of disambiguating between being in a folder:
> [screenshot]
…and being in a subfolder:
> [screenshot]
This makes the display of folders in the `<h1>` look like the prototype.
It alters the behaviour we’ve initially built here by only ever showing
a maximum of two levels of hierarchy (the current folders and its
parent).
