from the looks of it, that UOSA journal is insufficient for my needs and instead of being a reason for switching to UOSA it would be just another in the long list of reasons I can't. do you really have to switch tabs all the time to see the different messages? can you remove it from the game window? can you resize it?
Heh, I think you have misunderstood something basic. The EC chat pane is extremely flexible.
1) No, you do not need to switch tabs all the time. Each tab can have as many or as few channels as you like. By default, the Journal tab has the most used channels already present.
2) No, you cannot remove the chat pane from the game window. You don't need to, which is why I explained the fading to transparent, above. Note that the game pane can be resized within the game window, so if it really, really bothered you that they overlap, you cold move the chat pane completely off of the game pane.
3) Yes, you can resize it and reposition it. You can make it as large as you want, but I believe it won't go any smaller than three tab-buttons wide and eight lines high. (At least on my 1920x1080 screen that's as small as it goes. I suspect on smaller screens it would go smaller, but I don't know.)
4) The "chat mode" key is <Return>, unless you use chat in compatibility mode, in which case it is like the classic client with no special chat mode.
