No it isn’t. I’m referring to moving the entire topic to a different category, and leaving the topic title still visible in the original category listing, together with a link to the new category that it was moved to, like this:
For example if you moved this thread out of the “feature” category, I would like to see this topic still listed here, with a “moved” label and a link to the new category.
Shadow links aren’t just for the topic owner. They help other users who previously found a topic in a category listing to not lose track as well. Additionally it helps users understand what sort of topics aren’t relevant to the category, so they don’t keep posting irrelevant topics there.
Notifications aren’t enough. Many users ignore them completely.
