If you tap the "+" button, you get a new draft.
If you tap and hold the "+", you can access some additional options:
- New from clipboard: Quickly create a new draft with the current contents of your clipboard.
- New from selection: Create a new draft with the text you last had selected in the current draft. Great for breaking off a section of text from one draft to run and action or start a new draft.
- Import from Dropbox: If you have the official Dropbox app installed on your device, you will get this option. It can be used to browse and select any text file from your Dropbox and import it's content into Drafts.
