Row Height or Multiple Lines in Row

My wife is playing around with my second seat of Devonthink 3 to make a database of her artworks. Her complaint at the moment is that the thumbnails shown in the column view are too small to be useful. But if she increases the size of the font in order to make the row height larger, then the font is too large for her to be able to see all the metadata she needs at a time. Is there a way to keep the font for a row at a reasonable size, but change the hight of the column so the thumbnail is bigger?
