The current method of right clicking only on the little colored bit of a tab island and selecting "close tabs" which is one item in the middle of a list is cumbersome. First there should be the ability to close the entire tab island from any of the tabs in that island, instead of only closing that tab or the other tabs and so on.
2nd, I think some constantly used functions, or at least "closing the tab island" should be right at the top or bottom or somehow noticeably separated from the other options. An icon or several at the top similar to what Windows 11 does in the file explorer right click menu would be extreeeeemely useful and handy, I really hope this gets considered as the current method of "an unmarked item in a list accessible from a very tiny area" is not a great solution, it's really the bare minimum.

I suggest instead give the ability to turn it on or off. I very much enjoy the update sound even though it is a bit loud, I don't want it gone.
