As the leader of a big guild, i like to control the activity of our players, specially the ones being inactive for long time periods. Unfortunately the game needs an improvement in this department because we only have the 'Active: Yes/No' in the guild interface, and the green lights to check who is online.
Ive a simple and clean solution for this, instead of a green light for online members, have one light to every player with different colors accordingly to their last login. Heres a pic:
Blue: Online now
Green: Online in the past 24h
Yellow: Last logged 72h or more ago
Red: Last logged 7 or more days ago
Grey: Last active over 2 weeks ago
This could work for guild and also friends list, would help alot to control who is active and who isnt within the guild, instead of having to look everyday and take notes.
Ofcourse these colors and timings are just my suggestion, could be different if theres a better suggestion
