IMO the demo page shows many of the deficiencies of this over-complicated “packed tags” approach.
- Each time you select a tag, the appearance of the tags filter changes drastically, increasing your cognitive workload.
- You have to maintain your tags and put them into desired groups, which can be time-consuming if you have a large number of tags.
- The process of selecting tags from the side panel can be arduous if you have hundreds of them in each tag group.
This approach seems more suitable for smaller operations, e.g. personal blogs. I don’t think it would scale well.
