I find it somewhat funny that the macros that you want and the more bars for things are all under prefs that you need to turn on or off.
for macros, i just use alt and ctrl and 1-9. then again i am also a Final Fantasy 11 player that play wow pre cata.
yes the GTN need an overhaul. being able to sit in a chair would be nice someplace other than my ship.
as for other things, take a moment to look around your settings instead of having it handed to you on a silver platter.
also keep in mind that at this time the game is not officially launched yet.
