I've been using Opera since it was paid software on Windows 98. Now that I got a Chromebook I get a sidebar, which is not only useless for me but it can't be disabled, it's just sitting there wasting real-state screen even on fullscreen. I had to move to another browser not only on the Chromebook but on all my devices (since the Chromebook wouldn't sync my data anymore). Please, let me know when I can get rid of the sidebar so I can come back to the Opera ecosystem.
