I see you’re putting a lot of effort into the shiny admin dashboard which is great . One thing which was mentioned in a discussion recently purged away from alpha feedback - why not make these graphs and metrics available to the community too?
I’m thinking of the many contributors with higher trust level here, who may see indicators for a well-grown community, not essentially administrators only. Maybe have such statistics only available for a specific trust level configured in site settings. This allows to disable this entirely for sites which don’t like their data that exposed. Still I do believe that such graphs and metrics are great for the public domain.
This likely would require more than just caching the metrics and graphs, maybe a good idea to render the charts into static PNG on an hourly basis. This could prevent high loads on the server when many users click “about” or attempt to play around with DDOS in a curl script.
This is not an immediate request, first off the admin dashboard should be finished with 2.1. It would be great though if development and code would be prepared for such a thing on the long run
