I tried Sidewise, loved it and removed it from Chrome. Because after installing it, the "blue screen of death" appeared, forcing a restart Windows 10. My computer is very stable. I don't see the "blue screen of death" once a year.

Also, after installing Sidewise, Chrome often blinked like a strobe light. I've never seen any other software act like this. Also there was a 3/16th inch gap between Sidewise and Chrome that never could be closed. Sidewise settings were set to have Sidewise always attached to Chrome, but I'd have to start Chrome and then manually start Sidewise. I see Sidewise is in Beta. I'd pay for this Chrome extension if it didn't have so many serious problems.
