Hey tyw
Thanks for the feedback and glad to see that you're finding it useful!
We decided during the launch of the feature to just the popup box due to also using the feedback survey when the case is closed to save potential duplication of putting it on the case + in the survey.
As you're aware we are always looking at ways to improve customer engagement and I will add this on to the list of things to keep in mind when we are reviewing the case portal.
We will look to see if we can make the process more clearer such as adding additional text to the close case popup and also the documentation above 🙂
For now I would recommend to leave a quick comment to say that you were able to resolve it yourself and what it was that resolved it and then click the close button.
