How can I download the plots I generate in the notebook in the Beta version? In version 2.0, I'm able to right click and “save image as”. But in Beta, I don't see it as an option. 

Also, after I switched back to version 2.0 in order to download the plots, I opened the notebook and found all the code I wrote today was lost. I am certain that the changes I made today was saved in the notebook in Beta version, as I closed and reopened the notebook several times today and everything fine. The progress was lost after I switched to version 2.0 and opened the notebook. Is this a bug?
