P: Metadata, Marking, Keywording Sync between LR Classic and LR Cloud

I use LR Cloud-based mostly as a consultation and searchable image database for a company. So all the editing work like copyrighting, captioning, keywording, star rating, flagging... is done LR Classic then uploaded to LR Cloud. And it seems these 2 LR apps were not built by the same guys ! Metadata fields are very limited on LR Cloud. Also the search does not look into the copyright field, so I cannot display pictures by the author. The search by keywords (added in LR Classic) works fine with 3 terms, from 4 terms it starts to bring up images unrelated to the search. And if I return some pics - edited in LR Cloud - to their base (LR Classic), a change in the caption field is embedded, but any star rating change or flag change, is not ! Annoying... Plus, why don't you guys also add the color labels in LR Cloud? And, most ideally, if the exact same Keyword Hierarchy as in Classic could be created and worked upon on the Cloud, that would be most welcome too.
