I went through the ‘DSON’ product list, opened a new browser tab for every product. Then comes the magic. I have a tool (Chrome browser plugin) which lets me know, in-page, if I bought any item (or a bundle that includes that item) and adds a reset link onto the page for the product. I then closed all the tabs that I hadn’t bought, and all but one for each bundle, and then clicked reset on all those pages, and went through and downloaded everything that had the new files.
99 downloads, including the Poser Companion, the DSON Core, and the Legacy versions of all of them.
It takes a long time. (I did things a little differently, and had a separate machine on a faster link do the downloads for me, and I’ll sync the items to my computer later. Other folks could use Taozen’s downloader, for example.)
I don’t think it would be a good idea to auto-reset. Not everybody cares about those items… I’m looking forward to them getting update notifications working, though.
