Thumbnail size on Dashboard

In your latest website release, it appears that the thumbnails of the Most Recent Campaigns on the dashboard have been reduced in size, making it difficult to confirm a campaign. Is it possible to increase the size of the thumbnail to at lease the size used on the Campaigns page? Otherwise, the dashboard is less useful and I find I must click over to the Campaigns page to "see" the most recent one I'm looking for. Our workflow is to copy a campaign and edit to save time on duplicated material and provide consistency. The thumbnails help in identifying the correct campaign to select.
