My definition of multiple categories refers to the PureOS Store:
- Create
- Work
- Play
- Socialize
- Learn
- Develop
- Codecs
- Fonts
- Input Sources
Whereas, my definition of tags is your definition of services, categories, frameworks, mobile compatibility, and packaged in.
So, if you started to create categories other than “Apps” and “Games”, in a similar manner to the PureOS Store, then these tags become less useful due to redundancy.
