At present, you can change the message - Great!
But - it would be good to be able to change the style of the message. you may want to have different styles depending on warning, critical, adding, saving, etc. etc.
You can add each one of those style and call on them from the workflow. Use copies of the same workflow with different conditions to display the required alert message
Thanks Ali, I thought you would be able to do that, but it would be just as easy to apply a style at the same time as you edit the message, then you wouldn’t be cluttering up the UI with extra elements.
Can you use conditional format with a custom state that is passed in the workflow to change appearance?
Don’t know, maybe something I will explore as part of the bells and whistles! focus on core functionality at the moment.
