I hope I am not repeating things too much here...I got to about page 4 and stopped reading.

There have been some good suggestions so far: here are mine
1. Ability to name your weapons (this one was mentioned early and its a great idea. I have 3 sets of short swords, ruined ones for practice, regular 50 quality ones so I don't overkill a rat, and a set of 300 quality ones I use for those serious battles. Those I need to equip in a hurry with a shortcut, but the system cannot distinguish between the different short swords. I therefore have no control over which will be chosen.)
2. Potions or food that effect stamina. Just about every food you consume regenerates HP. But nothing for stamina?? Even water should help a bit. I would like to eventually see food items regenerate combinations of things...a little HP, a little stamina, a little mental stamina... Even a range rather than a set number of points. For instance, you eat an apple and you get 5 HP. Maybe next time its 3 HP. Not all apples are created equal. Maybe you even occassionally get a crappy apple, or a crapple if you will.

But that's more advanced stuff. For now, anything that will increase that annoying stamina.
3. More stamina ideas: Its great to see sitting speeding up stam recovery.

One more interesting concept in the interest of realism: less stamina used going downhill and more going uphill. It was always curious that I used the same amount of stamina coming down a hill. Shouldn't you use less? Again, maybe not so simple - a gradient would have to be identified and some sort of formula constructed to compensate. Maybe some day.
4. There are a few graphics issues around zone points. There is a jerky motion that occurs when coming out of those korogan passes. Its a minor bug but kind of annoying and its been present for years. Also the map change at bdoorsout to bdoorsin (I forget the exact names...on the path up to the fortress just past Raerul) needs to be tightened. I actually took a closer look around there once and fell through. Again, hopefully that's a minor thing, but you DID say easy.

5. Banking system. My mules have mules. Ok, that one is anything but easy.
Since that's a major feature addition, I'll offer an alternate:
5a. Resizing of all windows, especially the shortcuts setup window. The slot where the hotkey goes is very small. If you have it set to something like <ctrl>+a , you only see about <ctr... Annoying to set a hotkey, forget what is was, and have no way of seeing what you set it to.
Oh and while I'm at it, what the hell happened to Harvis? He used to be guarding the entrance to the bronze door canyon. Maybe we can do an RP event at some point and find him. :-)
