Enable tags or labels on topics?

Is it possible to enable the discourse tags on this forum? This would be useful for example to mark a question topic as “solved”, or to indicate common topics like “Physics”, “MatterJS”, “Audio” etc.

As far as I know it’s not possible at the moment. So I mean this could work in a similar way as the labels in the old forum.

Well, you can mark your topic as solved by marking an answer as a solution, but it’s not a tag.
