Some time ago was introduced the capability to send GB and trades as a message
This helps a lot, avoiding looking for players GB... so a great short cut.
Another feature that helped is the option to view player GB without entering their city... (also a great addition, avoids spending time looking for GB in player city)
One thing that we find missing and would be helping... What about adding other player as link in a message.
In my guild, we have a thread where multiple players add their names and GB they need help with.
Would be great if we could have links in messages as shortcut to multiple players or even GBs.
It could maybe added as something like this : GBname@PlayerName
