Applying 'Tags' to a post functionality

For Grimstill + Posterity, when adding a new tag in the input-field, the tag will only add to the list upon pressing ',' (comma). Are we able to also have the 'return' keyboard button add the tag to the list? as I found myself pressing the 'return' key expecting the tag to add.

Not critical but food for thought as we develop Posterirty.
