Is your feature request related to a problem? Please describe.
When there are connections to multiple hosts for the same network, they're indistinguishable in the side panel.

Describe the solution you'd like
Users should be able to join a network and not care about exactly which host they're connected to.

Describe alternatives you've considered
N/A

Additional context
Might consider an approach similar to HexChat which maintains a file to group servers by network.

Might be able to add secondary text with the hostname (similar to what's done when a channel is favorited)
