How do I delete a sketchbook?

I’d like to delete several sketchbooks I’ve accidentally created!

Hi @timdevg If you select the sketchbook you’d like to delete, then drag the orange menu to the left then you’ll see the delete button:

Thanks - easy when you know how (i.e. dragging the menu). I guessed there must be such a button to the right somewhere, but every time I tried to click on the arrow to show it, I of course ended up creating a new book instead…!
