I also have some issues with the chat filters. The basic player chat ones are fine, but all the system messages, battle spam, trade spam, ect seemed difficult to determine which filter controlled which. Like if I open a chest, I get a message that I have recieved an item on one filter, but the actual "you have found THIS" item name comes up on a different one. Which leads to why I would like to see multiple window at once. I don't want to have anything but player chat in one window and spammy but possibly important stuff in another, and I don't want to miss anything by not having that window visible all the time
