Resizing the Dashboard Boxes

It would be nice if it were possible to resize and/or rearrange the Dashboard sections like tiles. I am not salesperson who often has appointments. I do have often have a list of tasks to reference. So I would put those in the top left with recent activity beneath it. I would then have Appointments in the top right and I would shrink it to a small window so I could have more room for a bigger window of the Notifications beneath it. It would definitely be more valuable to me to be able to see a longer list of notifications right away without having to click on "Show More".
