Just thought I would share a useful tip for the Gallery. You may find that you want to see more than the top 10 newest items or the 10 most viewed items. We'll be adding a more link to the bottom of those in the near future but in the mean time you can see this by using a trick in the search bar.
Enter a space (the actual character space with the space bar) into the search control in the upper right corner of the gallery. Then press the search button. You'll get back a list of all the extensions since all extensions will have a description with a space in it. Now sort this list by the column you are interested in, modified date, number of views, cost category, etc.
