For some unknown reason my JL page now has the area circled in red permanently displayed
I want this “sidebar” to disappear, so that the full page is for text, and I am sure there is some way to do it
If someone could advise me, that would be kind
I did not change any settings, and cannot find a JL “settings”
Click on the stack of three horizontal lines above the sidebar area you circled, and it will go away.

Have you tried clicking on the lower right double ended arrow?
When I first log in that sidebar appears but only for a short time <> 3sec.
Perfect answer thanks
Have a cyber beverage, or a real one, good deed for the day done
