Okay, here is what I've been hearing from the few people who've been playing Classic recently.
- There should be a filter or tabs to separate 'toall' and 'toguild' messages.
- There needs to be a way to copy/paste text from the chat box.
- Mass messaging needs to be displayed on the minimap, as well as toguild messages if no filter/tab method is applied.
- Clicking on a player's name in the chat box should always bring up a PM window (like it does for incoming PMs).
- Complete customization of the chat box (alpha, color values, size and position on screen.
I will update the list as I get more input.
