I'm concerned about how long this feature is taking to be developed. I bought Affinity Designer 4 years ago thinking it could replace Illustrator in workflow however without features like these it isn't usable in industrial contexts. For example, you get a technical drawing in pdf vector format, it reads as a layer per vector object. However you want to re-build the layers which happen to be colour coded. Affinity Designer while good, hasn't seen many improvements beyond bug fixes since it release. I agree with @toltec on his/her pile of features we're **still** waiting for.
