Yes, see the link at the very top of this topic, that refers to the topic about that. @Mittineague wrote a plugin in 2015. I was using it and then I found out that it needed to be updated (it hadn’t been updated for over 2 years).
The next step was me realizing that this could be done much easier now using a theme component.
Yes, I had started to update the plugin to take into account the changes in the number and locations of plugin outlets a few weeks ago, but other priorities moved it down on my ever growing todo list.
If the same information can be provided as a theme component that works in the GUI and doesn’t require editing app.yml and running launcher I think it would be easier for most. I may be wrong, but I have a feeling most prefer GUI over CLI.
