Note that our proposal is just a "fast-path" for the API of the Dictionary, for getting access to the resources using symbols (IDs associated to strings) -> NsCore/Symbol.h

But. with this approach, nothing changes on Studio side, where entries are still strings.

Not sure if this matches your expectations.

I will take a look and try Symbols out! But I think there should also be
BaseComponent* ResourceDictionary::Get(const Symbol& key) const;
next to
BaseComponent* ResourceDictionary::Get(const char* key) const;

And I would suggest something similar for all functions wanting Uri for argument

Also, exposing how SymbolManager creates an index out of the string would be nice. Like a callback function would maybe be nice, if not changed it uses yours native one. Because every game has its own way of creating a "hash" and in this way we get more freedom.
