Add 'Close All Other Pages' &/OR 'Close All Pages' to File menu

Many times I’ve been in and out of multiple pages and that leaves them open in the canvas, so that there are many page tabs in the canvas.

I feel it would be a great addition if you added a ‘close all - except currently open tab’ feature, which I propose the name of in the title above.

I’d also suggest a ‘Close All’ too.

Thanks.

File → Close all files

does this.

Don’t see that.

Oh, looks like it only shows up when using Flexible UI
