Where to add header items for block?
Where is the _right_place_ to insert addHeaderItem() calls to include stuff that _only_ my block's _editor_ will require?
There's no way to do this when creating a custom template for a core/package block type without overriding the controller. So, you either have to obscure the upgrade path by overriding an important file, or echo the script tag directly in the block view, which I think is messy.
in on_page_view() but not inside view() or am I missing something here?
