Create plugin with multiple panels

Hi, I saw this but it show an example for a plugin with multiple tabs.
I want to have a plugin with multiple, independent panels.
Where can I find and example or explanation how to add entries for another plugin in the index.js and the changes required in index.html.

Check manifest docs for entrypoints. You can have as many panels as you wish. Also check plugin samples on GitHub - lots of them have multiple panels

If you plan to build responsive panels, be aware that media queries might not work correctly for multiple panels:

It has been over a year, has someone tried it out since and knows if this got fixed or not? (I’m still using the workaround with the resize event)
