Still wanna have crt-checked hubs to be marked somehow inside the common list of hubs.
This list?:
https://dchublist.org/hubs
or this list:
https://dchublist.org.hublist.xml.bz2
In the first case yes it will be done with an icon and cert download link later on.
In second case it could be done using only some icons that work via xml without breaking it. Still doable but this needs more coding than above.
