I love these buttons but I really wish there was also a close tabs to the left button. I can't understand why there isn't one. I have to use a separate add-on for that and it spoils the 'theme' of all your other tab buttons that I use. Being able to change the icons would be a fantastic feature.

Thank you! This is very useful. Is there a way to trigger it with a keyboard shortcut? It would make it even better..
