Closing parts of Editing By Acident

Hello, recently I keep by acident closing important parts of premiere which make it easier to edit clips. I by acident closed the menu that plays the video clips in editing so I have to go back to learning to try and see what im editing which is a pain. I also by acident closed the mini effects pannel in the bottom right corner which was helpful too. I added some screenshots of the things I closed and by I acidently clicked.
