What guild Improvements would you like to see in ESO?

Onward since Elsweyer Launch, as Guild master myself I have gotten over 200 number new member with over nearly 400 member activity rate. I have seen expansion of people wanting to do content together as guildmates and actually doing things together! 

I think in long run, having guild finder will making group engagement in eso skyrocket. Still I think there still room for improvement.

• Guild Calendar
• I see the Guild Calendar as necessary addition now only for guild officers, but so people can share what they are doing and others can join them on adventures.
• Guild Sign Up Sheet
• I would really think having a sign up sheet available in game, will make people do things across zones more, even if the rewards are questionable in older content. There's something special if you can do it with friends.
• Guild Mail
• This is just extra that can come eventually but would be nice to share special movements and tell people's what is happening in guild
• Guild Quests
• Not necessary questions, but it would nice to give guilds goals to work together towards. Something they can feel proud they did together.
• Guild House. 
• Big talk but would like to simply give selected house to guild and other people be able to add things to it. Not as important as the other things, but hopefully one day!

Do you think it's important that we have more guild improvements or are things fine as it is in ESO? If you agree towards improvements then what do you think is important to see? How will it help your ESO experience?
