UI, Social List, Linkshell and Party information in chat log.

Sorry If this has already suggested, but it would be great to be notified of other players online status in chat log. An small text showing who has logged in, who has logged off, who has joined linkshell, who has disconnected... I also would like an small icon (like the npc linkpearl one) flashing when you have an unanswered /tell. This will help a lot in all kind of ways, as you always have to wonder where did that party member go while doing certain events, if he/she left the party or disconnected. Also would help stop checking the social list often to know if your friends are online or not. Kinda like a log based messenger information. Not sure if it something to develop or if its something that can be added right away. Thank you!

If you add a chat tab with just /tells and filter the /tells out of your other windows, I believe the tab will highlight if it has unread /tells. Granted, then you're less likely to see them in the main tab. It might still work with the /tells shown in the main tab, but I know that functionality is kinda there. Give that a try.

As for the LS-logon notification, I strongly doubt the framework is there to support it. Most of XI and XIV is oriented around pulling information, not pushing it to the client, and you'd need push notifications for that.
