Hey Cyclopropinon,
Thanks for letting me know about that sorting bug, I've fixed it now.
As for adding the snapshot list from WI Mods to WurstClient.net, there is a technical reason why it doesn't have it. While the WI Mods website uses Hugo to make that detailed snapshot list possible, WurstClient.net is built with Jekyll instead, which is much more limited when it comes to generating list pages.
I should also note that, after making that snapshot list for WI Mods, I realized that this is actually really bad for SEO. Google's system can't tell the difference between all these different snapshot pages, so they exclude most of them from search results and complain about "duplicate content" in Search Console. And so if you google for a specific snapshot version of WI Zoom or Mo Glass, it just won't find the right page.
Because of these issues, if and when I figure out a way to let you filter by specific snapshots on WurstClient.net, it will probably look very different from the snapshot list on WI Mods.
