ISO: hierarchical tags
One thing sorely missing from Mi Yodeya is a tag hierarchy. For example, having the Book-of-Judges tag be a sub-tag of the Books-of-the-Prophets tag, so that keyword searches among the latter will find also questions in the former (or will optionally). As another example, having the labor-of-writing tag be a sub-tag of the labors-of-sabbath tag. This would allow someone to find all questions about a fine point of the labors of the sabbath even if they may have been tagged with a specific labor's tag.
It doesn't seem like Codidact — or at least not Judaism Codidact — has that now. I would like to put it in as a feature request. Any chance? Please post replies below if you can provide info on the likelihood of this happening; but also your opinions on why this would be a good or bad idea.
