A couple of questions about Google Docs

The questions will be about features that after upgrade can't find:

1. You used to be able to highlight a portion of text and mark it as "Quote". In old documents such possibility remained. In the new it is not.
Included: Format — paragraph Styles — Quote

2. Old documents are in the form of infinite canvas. New documents are A4, А3и etc. As these formats are disabled and used the old settings?

Thanks in advance for your answers!
