Feature: implement marker color systems #11
Description
- if the node is using TCP/UPnP to connect to the network and the port is open: Green marker
- if the node is using registered on the Bridge API but the port is closed: Red marker
Another example would be to use this type of system by say last node activity:
- Node is active: Green marker
- Node has not been seen in the last hour: orange marker
- Node has not been seen in the last 24 hours: red marker.
