Dude, you have issues...
with npc chat. t omake it easier why dont u just have a box come up with the npc dialogue u can possible say to him. like hello and usuless things owuldnt be there but just quest stuff. so its a bit easier to do atm its rediculous
The idea (I think) is that the Main tab will be customisable in the next version, so you can make it your 'All' tab if you want, or just have it as plain 'chat' if you want.
