Option to change enter key from sending to creating new line?

I am running a test of Openfire and Spark in my company. Several users have asked me if there is a way to change the enter key from sending the message to just adding a new line. I believe they are used to that from Yahoo, which gives you that option. Could that be added as a preference?

Hi,

I’'ve filed SPARK-745 to add this feature.

Cheers,

Derek
