cannot widen description column

In the issue navigator, the description column is always squished. I would like to configure issue navigator to recognize that I would like to make that column wider, but I already know that's not possible. One of the users here suggested re-naming the "Description" field to "Description (long)" so the width would force the browser to make it always wide enough to hold the title. But I can't find how to rename this non-custom field. Does anyone know how to either do that or force the width in the issue navigator to be wider?
