Hi, I use nested categories and tags in this style:
Category A
Subcategory1
Subcategory2
etc,
Sometimes I use the same subcategory name within different categories. Although they have different colours it gets confusing to remember which subcategory belongs to which category. So, I think It would be useful to get Category and Subcategory column in view (the same goes for tags and subtags). Or, there would be possible to view expanded/collapsed Category or Tags column?
