We should be able to link not only items, but even quests, actions etc.
And i hope they will implement "right click feature" .. For example: right click on a character to see
all the possible interaction, like invite, follow, tell, examine etc.
Last thing i would be able to click on character names in chat to tell them directly, or right click on them > invite..

Well all these things should make ffxiv ui at least at the same level of other mmorpg.
