No particular reasons, and the (!IP) was just an example. I may want to send other (maybe) more useful tags like (!T), (!VER) or a (!X...) tag. Just now I don't know. Of course I see no utility to sending bold texts or sounds but commands like /block, /viewlog or /info may be useful. Also, the text recall feature. Well I don't know.
Anyway, the main pourpose of the thread is make sure Patchou didn't add the Plus features to that window on pourpose and not because he forgot to do it. It'd be great if some tags or commands would be added, however I don't care, because I don't use that window. (if was only yesterday, he send me a message from his phone and that window opened
)
