Стало удобнее пользоваться в контекстном меню, но надо нажать мышью 2 кнопки. Хотелось бы назначить эту функцию на какую то горячую кнопку на клавиатуре.

If only you could bring back the 'o' keyboard shortcut for the Close Other Tabs menu item, this addon would be perfect.

Perfect, lightweight addon that does exactly what it says. Any chance you can add a shortcut key (for the "o" character to match the original menu item) like you did in close-tabs-right extension?

"About" says that this extension hasn't been tested with Tree Style Tabs - I have only just installed it, but I use TST, and wanted to report that, so far, it's working perfectly. I'm disappointed that an add-on is required to restore this feature, but grateful for the fix.
