While perusing this page at https://dev.tiki.org/Farming-Automation

I noticed this:

Goals of Automation

• Autonomous completion of tasks
• Remote control (i.e. from Tiki site)
• Swarm application (i.e. swarms in nature)
  • i.e. all drones connected (via code) and working as one unit in real time

The neat feature I am talking about for some reason is not showing here in this topic, but I noticed at the link for "swarms in nature" there is a little circle icon when hovered, displays the links source, in this case "wikipedia". How do you get that little circle to appear before the link?
Thanks folks
