Hi!
For FHIR STU3 there a Simplifier project of FHIR core called Core StructureDefinitions - STU3. From there we have used a lot of profiles and extension. Now with the new release of forge for FHIR R4, most of them can't even be opened in Forge. Does any one know if there is a plan to create the same type of project but for R4? Or is it possible to continue using and referring to profiles and extension from STU3 while using FHIR R4?

For example, we have a Patient profile buildt in R4 in which we like to add an extension to the given name called EN-qualifier (http://hl7.org/fhir/StructureDefinition/iso21090-EN-qualifier). EN-qualifier is one of the extensions in the project Core StructureDefinitions - STU3. Can I continue using it in my profile and how in that case? Or do I need to wait for a new Core StructureDefinitions project for R4? Or even create my own extension?

Actually we published the core resources for R4 on Simplifier this morning.

I am still in discussion with Grahame to publish the spec under the package name "hl7.core.r4.*". The big issue here is that Grahame wants to publish that as one huge package. Which results in slow behavior for Simplifier and the clients we tested with. As a result, for the time being we published them under the Simplifier namespace:

simplifier.core.r4
    simplifier.core.r4.base
        simplifier.core.r4.resources
        simplifier.core.r4.types

    simplifier.core.r4.tx
        simplifier.core.r4.v2tables
        simplifier.core.r4.v3codesystems
        simplifier.core.r4.valuesets
        simplifier.core.r4.conceptmaps

    simplifier.core.profiles
    simplifier.core.extensions

    simplifier.core.r4.searchparameters

A single reference in your project to simplifier.core.r4 should be enough:
https://simplifier.net/packages/simplifier.core.r4

personally, I don't understand why there's a claim that it's slower.

it seems faster to me
