It's not really "chat" it's just (ostensibly offline) messages. I'm aware that you can send messages regardless of your status, but it's not as seamless as a real-time, updating chat log.
The updated app is a lot smoother, but still doesn't have chat.
what i guess i don't really understand is you are saying the messaging isn't chat (while technically it is but we can look past that for now) but you have a chat feature on the phone.
in your example, you are saying that if you are on the computer and you are on facebook chat with someone, the messages you send do not show up on the messaging text app on the phone.. while their replies do show up (this is the case with me at least). However, if you transition to the phone for on the go, you can message from the app and it will show and then it will also reflect on facebook itself. The history is saved and viewable anytime from the facebook app by microsoft.
you say that it's not streamlined (the messaging app) like a chat program but if you are trying to chat from your phone, why are you using the messaging portion of the facebook app and not the messaging app that is on the phone? I guess you are looking for a unified answer (though facebook chat and the facebook app are also 2 seperate things on iOS even though it does show your message updates via the facebook app itself. I know this coming form an iphone 4S myself) but that is just not the case in Windows Phone.. and as many are showing here, it doesn't seem to be a major issue for most current windows phone users, just some getting used it.
If you can still view your history from the facebook app itself, i guess i don't see why you also need it in the messaging app. If you are looking to reference a previous statement or something, you can still go into the facebook app and copy / paste the messages (or screenshot or whatever) you want and use it that way, or to read all of your messages on the go.
Im not trying to be rude or anything, I just don't understand what you are trying to ask for since you are asking for features to be in 1 app that are located in another app. Since Microsoft made both apps, they know what both of them have and made them work in that way and not duplicate the feature.
I will admit that sometimes it's odd that im talking to someone on FB chat on the computer and when i check my phone later, i see all of the messages they sent me and none of my replies, but i still have my replies they are just in another app tile a few inches away. Just a difference in how you access it really. I personally wish that only if im talking to the person on my phone on FB chat that their messages would show up in the messaging app on my phone and maybe someday we will both get what we want via a settings option.
Heck I want the messaging app to support more chat programs like skype too
