I hate the latest software update to my Samsung Galaxy 6.

I really hate this new software update!!! I used to be able to see if I had any new text messages simply by looking at my phone - there would be little orange bubbles on the apps in the task bar at the bottom of the phone.  Those are completely gone now!!!  Also, when I open a menu, it stays open until I close it, rather than just closing automatically after I select an app from the menu.  Is there any where in the settings to change these features back to how they were before?
