show posts not letting you jump to up but letting you read it from the last tweet you have read and remember the last tweet you read

hi i have an idea about , when you press it you see the tweets from down the last tweet you were reading before pressing the button and continue reading from down to up in till the last tweet when you pressed the button and remember what was the last tweet before you close the website and continue from there till you reach the last tweet, i really hope that i explained it very well.
