Instance features to display

[Nutomic]

In the instance list we have space to display three different features in the current layout. There are many possible options here. The Piefed instance chooser can also be used for inspiration.

Some ideas worth considering:

• Instance age
• Uptime
• Additional Lemmy statistics once available (Provide more statistics lemmy#6288)
• Ping each instance and show an icon for those which respond faster (are closer)
