Command /favor (tells you who has favor, like the ToA message)
'
Automatically move "WTS" or "WTB" announcements to the trade channel (seen a lot of demand for this on this forum, though this might be a better solution than others suggested)

special command for selling. Heres what i mean: say you set up SHIFT+RIGHT CLICK to automatically post that item for sale in the trade channel! (i hate typing) the announcement come up "WTS Long Sword of Enchainting 15-22 Ench+20% ... <all wep stats>", then you hit <enter> and its posted!

Designate items as unsellable (I'm always paranoid that im gonna sell my greens to the merchant)

Buy extra storage space (maybe make the cost exponential, 1 extra row 1g, 2nd 10g, 3rd 100g, 1k, 10k, etc...)

Store/save builds. (again a lot of demand for this in this forum. I would love to click on 1 tab and switch my necro from SS build to an MM build, switching spells, point allocation and mybe even armor...)

Change name. Namechange should not be easy,but should be possible - maybe awarded after a really diffivult mission (taht has to be completed solo?) or make it cost a lot of money (100k) so its not worth it to get anotehr name on a whim. After naming my characters really boring things, i wish i could change it, as more inspired names come to me later.

Just think of the poor people on this idea here. This game was originally intended for people, no matter how rich you are to be on a level field. The storage space just benefits the rich, but in a way pretty well disadvantages the poor. Namechange is a cosmetic thing, but 100k is quite a lot. Hmmm...15k armour or namechange? I would say 10k, only once a month (this does NOT accumulate) and cannot be done up to maybe 1 or 2 hours after a trade to prevent scamming. Solo missions are not part of the gameplay either.

Other than that, I like the rest of your ideas and a few tweaks could fix storage and namechange up. I'm always worried that when i find like that sup vigor or once a sup smiting rune i'm gonna sell it by accident. PLEASE let us make our own things unsellable Anet! PWWWWWWWWWWWWWWWWWWEEEEEEEEEEEAAAAAASEEEEEEEEE?

I'm all for these:
/favor command
Unsellable items
Store/Save Builds <-- Discussed a lot here..

I'm not so sure about the others..

I like them all except the storage prices, there should be more but not like that.
