I like this game very much but i am getting upset when i have to ask who is online all the time. And people in clan are getting upset about people who asking who is online all the time. I think solution could be little dot beside the player name or beside donates, that comes green or red if player is online or offline. It should be only visible to other members of clan or even co-liders only.
And private messages, even if message had a cool down period 12h it would be very helpfull to send it directly to the player who wasn't reading chat for long. Saying for example last worning before kick or asking what happend he/she was out for so long.
Option to search other player by name. Just like a clan. Some people leave or are kicked out and it is almost impossible to find them if they were kicked by mistake after their name is gone from chat.
I think this options will increase integrity of clans and give liders better control.
