General Performance
I have noticed that RtP is not entirely responsive or snappy. It briefly hangs when closing chat windows or the application itself, and it hangs when starting up in order to load user data. Simply put, it feels a bit slow.
I'm not sure if this is a server issue or an application issue. RtP could be hanging in some cases because it is awaiting a response from the server, in which case you might want to consider asynchronous loading. I tested RtP again this morning and it feels much faster than it did during the weekend, so I imagine that the sluggishness I have observed is server-related.
