In Marketplace > Install plugins, it would be nice to show plugins authored by "matomo-org" first. Or alternatively show first the plugins that were most recently updated?
When visiting the Install Plugins page of the Matomo Marketplace plugin, other plugins unrelated to Matomo are showing. For example, one of my sites is recommending lots of Genesis plugins; I'm using the Genesis theme. Based on the Install Plugin URL, I think this might be related to the framework being used for this feature: http://tgmpluginactivation.com/
Upon further investigation I can confirm that all of the non-Matomo plugins listed on the Matomo page are the same as the ones being listed on my theme's recommended plugin page. The themes recommendation also appears to be using tgmpa but is only showing Genesis plugins, so there must be a way to limit conflicts.
There will be a first release from RC1 from 3 May 2022 with the release on 24 May 2022. This means we probably need to start working on this soon.
Many people will upgrade to WordPress 6 quickly so we need to make sure that everything works nicely with this version on release day (and ideally bit before).
We have 2 dependencies that hook into WordPress around updating plugins etc so I assume there might be some updating needed (or not but in any case should test it still works).
