Upgraded to 7.6.2 and the ability to create a new template email within the Workflow module only provides HTML or Plain Text editing. If you press the Create button at the top of the pop-up window it places you within the Email Template module (within the same pop-up window) where you get the new tile based editor.
Workaround to create templates in the Email module and then select them in the Workflow is working but it was nice to work within Workflow and create email templates from there.
Any way to allow the new editor to be active within the Workflow module targeted pop-up window would be helpful.
