A symbol for on line player

i have faced this problem in many clans even in my own new clan. some players are on line they may invite players unnecessarily or donate something else what is not required or not mentioned. i am the leader of my " HADES' HELL" clan. when i asked who did this. i may not able to get the answare all time. when i was online i saw one player's joining notice and immediate leaveing notice. my clan was closed at that time. so i didn't ask to that player.i am sure any of my player invite him/her. hence,IT WILL BE BETTER IF I SAW WHO WAS ONLINE IN THE PLAYER LIST (a green light like facebook chat box. but this feature won't get off by any custom setting). i am playing this game since long time. i got many updates. see the changes which i really appreciate. i wish some thing i will get about this kind of problem in someday's update too. my english may give u a headache but i am happy that u read it. thank you SUPERCELL. good n8. :)
