Add option to center Document Grid on page (instead of aligned left)
Please add an option to center the Document Grid to the middle of the page. That is, instead of the origin of the grid being placed at the top left of the document, have an option to place the grid origin at the top center of the page. This way, extra space that "overflows" the grid is evenly distributed at the edges of the document (as a kind of default gutter), instead of the current behavior, in which the grid is aligned to the left edge of the document and any "overflow" space is only on the right side of the document.
This is desirable when you want keep a certain leading between lines and create a grid based on that leading without having to adjust the leading to create a grid that perfectly fits the outer dimensions of the document.
