Extended Friends List

From one of the posters in general forum what got to my attention, that he mentioned a friends list coming up in PoE, so I have suggestion for that list:

When you click a friend on the list, you can type in a special column a custom text so that you could put comments for individual friends.

Ability to sort the columns A-Z text fields and number fields 1-9..999 as well as the comment field could be sorted A-Z

A column, that shows when the person was last seen online or for how many minutes/hours/days he has been offline. If the person is online, then there would be "Online" text in that column.

If possible a column, where you can see in what area/instance is the person located if he is online.
