Electrum-Servers have to operate a full Bitcoin-core node.
In the light of the recent events on the Bitcoin network, and the short fork on the network, it would be great if the Servers would advertise in their console (tab) msg (where they list their donation address) the Bitcoin-core version they are operating with! (or if they are using Bitcoin-XT...)
You can get that information for all servers through IRC (/whois server_nick)
But it would be nice indeed to have that show in the console and/or server list dialog...
