I just tried it, and it is not worth it, it just shows flat column of favicons without titles, it is better to install TreeStyleTab and disable OS window titlebar like this https://i.imgur.com/jnEXiPU.png so address bar in custom titlebar height is only 34px. I hate material design that still echoes useless whitespace everywhere.
