Installed it after hearing great reviews, and so far I really like it.

Najlepsza!

Excelente aplicación para las personas que abran muchas pestañas y no perderse, igual se le puede asignar un atajo de teclado para abrirla y cerrarla cuando quiera.

Love this addon! I want to contact the creator to tell him about a bug. When you close nested tabs you get a warning that you are closing multiple tabs and you can click a box to not warn you again. No matter how many times I click that, it still warns me. I had to turn it off deep into the settings of the addon.

This extension is very useful for being productive!

This plugin is fantastic! Took some time to get used to, but this is such a superior way of organizing tabs! Just be careful not to build too many, since it's effective at doing its job lol
