If projects have a development standard for widgets, like placement of paging buttons, you may write them down but still need to assert that they are applied.
How great would it be, if you could define this within your project or within a module as a default?
You want your Pagination default to 'Load more' in your admin module? Just set it in the module settings.
All your apps should use paging buttons top+bottom? Configure that as default in your app template.
Many settings that do not depend on the widget context could benefit from using a global default.
