Note:  access to the former site has now been discontinued.

HD is available for purchase in the store: http://www.herogames.com/forums/store/product/1-hero-designer/ 

The stated link (above) works just fine.  Not that I disagree with downloading upon purchase and maintaining your own backups.

The link included in the main post will be kept active for another month before being taken offline.

There is no way to access the old HD Vault, though users may post items that they have from the old Vault into the Downloads section (and have been), so files that you're looking for may become available over time.

The search function is about as close as you're going to get to the sorting that you're looking for....and depends largely on the extent to which the file uploader uses the tags that are available to them.

The link is in the main post:  http://www.herogames.com/userCP.htm

The look of the site (theme) is currently pretty basic (left to defaults for the most part).  We will be working on this over time, presenting multiple viewing options.
