I know that autopausing only appears in singleplayer. However I would prefer to have no auto-unpause.
I know how to change between the chat types.
Pro Console chat design is a bit better, while some might consider the border as disturbing. Clickable lables' design is better in Chili Chat imo. Also Chili Chat can be made scrollable from the start while Pro Console chat has to be swapped to the scrollable view every game. However the only really important difference between the two types is that there are separate windows for chat and other messages in Pro Console while they are combined in Chili Chat.
Atm I would prefer having all in one window chronologically ordered where debug messages have smaller font instead of messing around with multiple windows. Using Pro Console may be an option on a bigger screen or when debug console autohide/forceopen is available. (If you don't want to see debug messages, the difference is not that big anyway.)
