We wish full text search would look for about pages. This might be tricky because we don't want pages from every site duplicated. So we search none.
We could probably do better if a server assembled and maintained a search index for all installed plugins.
We experiment with this the long way by creating a site that has exactly that. github
We use an html script to fetch the about page for all of the plugins available on this server. This is downloaded as an export.json file which we install in a new site, one by one.
We wish full text search would look for about pages so we put them here as an experiment.
We announce this Sunday evening. matrix
