Issues in ICS update for Xperia Arc

I am using Xperia Arc. I have done the ICS update recently and I am totally disappointed with this update. The thing is some features already there in the 2.3.4 version of android is not there in ICS update.

1. When long press the power button ‘take screenshot’ option was there in the 2.3.4 but in ICS that option is not there.
2. I have seen the beautiful lock screen in ICS forums but it is missing in the ICS update
3. Music player is still same like 2.3.4 android version. I was expecting the custom equalizer as like Arc S . but it is not there in Arc ICS update
4. Google says recently opened apps will be displayed in the home screen in ICS. But its missing in the my ICS update.
5. Google says live and transformation effects are there in ICS but I am not able to see those things in my Xperia Arc after ICS update.

Kindly let me know is there any solutions for the above issues..

Thanks
