After playing for several weeks, I have come with some suggestions from my players.
This suggestion seems fairly straight-forward: In the text chat window, add an /occ command that would mark out an out of character comment or perhaps switch the typing back to the player's log-in account.
My players find it cumbersome to switch back and forth with the drop down menu box, so adding such a command would make playing smoother for them.
Relatedly, one of my players also suggested having OOC be toggled by radio button: have a radio button next to the drop down menu of characters to chat as, and if it is selected as OOC, all text would be displayed from their log in account, and if it was toggled to the IC state, that would have the menu drop down attached. This would make it easy to switch back and forth rapidly without having to scroll through many different characters in the drop down box.
