Nice - but my large thumbnails are now only half the size that they were with V107.
Then they were likely way too big in 107. One of the problems with the thumbnail sizing in previous versions is that you'd often get thumb sizes that are too large to be thumbnails if you chose the large size, and you could sometimes only fit 2 or 3 across. They are not supposed to be image previews in the thumbnail grid. We have other features for that like the preview/add feature (P+ button) or even Instaview (holding left mouse button on thumbs).
