Also not for the FB. The whole notification / feed UI is incomplete compared to #N9, where they were all compiled to one screen.. and where each the notifications where active elements from which you could get to the "content" directly. The Twitter feed that is accessable from the Notifications view shows only 10 latest tweets. And interaction with those is nowhere close to being comparable to Tweetian or QNeptunua in N9.

I hope the future updates of OS fix these issues. Atleast Tweetian port is at works to become availble to Harbour, soon
