Non-cryptic way to add spacing in a View or Group

[mdickinson]

Some of our project code has views that resemble this:

        View(
            VGroup(
                Heading("Some heading"),
                HGroup(
                    "15",
                    Item("my_interesting_trait"),
                    "15",
                    Item("my_other_interesting_trait"),
                ),
            ),
        )

Those "15"s are cryptic, and hard to do a doc search for. The meaning is documented under the Item docstring in the API docs, but you still have to do some guessing or code diving to even think to look at the Item docs.

It would be nice to have a non-cryptic alternative to these, e.g., something like Spacer(15) or Padding(15).
