I have just updated to Opera 25 and i cant find my saved sessions ? Is it possible to retrieve them ?

Has the notes feature disappeared as well ?

In addition the panels on the side no longer show a list of opened tabs which was the quickest way to find the tab you were looking for. Now i have to go along the row trying each one.

Opera has gone from a great research browser to a lightweight app.

Can anyone explain what this is all about as am unable to find any info.
