The reason I tried to delete them in the past is because what you say is true, but it tends to leave random vertical (blank) spacing in the place where it thinks something should be. I guess I can live with that but I am still working on trying to create 1 new template - for a week now. IT SHOULD NOT BE THIS HARD. The templates do weird things, like showing an item centered in the preview, then it isn't centered when it hits eBay. Not centered when you are creating the listing, centered in the preview, not centered on eBay... on and on for a WEEK. Why is it so finicky??
It should be simple - place the cursor in the item description window, hit the centering button, insert the table, done.
