Ignore a tag

I've been away for a while and it seems while I was gone that categories got replaced by tags. I like the idea but it would be nice to be able to hide or ignore a tag so posts that are tagged a certain way won't show up in the "All Questions" tab.
In Vanilla 1 it was possible to hide categories in this way. It would be fantastic if tags followed a similar design.
UPDATE: Case in point. I would like to ignore posts that contain the "test" tag as it is mostly users who are testing the system and haven't begun to contribute to the conversations yet.

Categories are still part of the core, and we're planning on improving them immensely over the coming months.
As for allowing blocking of tags, I wrote the tagging plugin, and I don't want to overcomplicate it at all. However, it is open-source, so you're welcome to either write a companion plugin or branch the existing one.
