Would like the ability to create, modify and manage email message templates on Nintex Workflow for Office 365, for the Task Process and Assign a task workflow action(s).

This is already available on premise, and is a very useful feature, but for people making use of Nintex Workflow for O365, this would most definitely make workflow design quicker if designers could choose an email template, perhaps containing some html and rich text/images (maybe even an email signature) where all they would need to is insert their metadata where necessary.
