Calibre Interface change description to right of book list.

[Katlurkin]

My last computer died unexpectedly, but fortunately I had backed up my information and book library. I have a new computer and downloaded calibre.

However the information/description for each books is along the bottom under the list of books. I had it on the right side of the interface next to the book lists on my old computer.

I remember vaguely fixing this with my last computer years ago, but I don't remember how. Nor can I find the instructions anywhere.

I would appreciate any suggestion to fix this.
