You can suggest features that could be part of Edwiser Site Monitor plugin.
Roland Sherwood, a Edwiser Site Monitor user suggested this idea in Moodle.org.
We are open to collaborations or partners, with whom we could develop and roll out features like these.

Same here 🙂
I'm using Moodle 3.5.2 and Edwiser 1.0.2
With Clean or Adaptable themes, grey panel but with Boost theme, it works. So investigation still in progress, but it's theme related as mentionned by Rahul.
