Encoding in the WordPress 3.9

Hey is there a way to get the program to utilize the options that it had before? For example I would like when I upload an image to see the image in the post box, rather than the encode code. Also, keyboard commands no longer work like ctrl+b, +i, etc. and I cannot center font. These are the main issues I have with the new version. How can I do these things without having to mess with encoding?

Thank you.
