Has Salesforce has said anything (officially or unofficially) about whether or not Lightning will support the below features that currently you have to switch back to Classic to manage? I have not been able to find an answer anywhere, other than that they are on the "Point-and-Click Customization: What’s Different or Not Available in Lightning Experience" list.
- Field Sets
- Apex Sharing Rules
- Apex Sharing Recalculations
Specifically, has there been any indication whether they will end-of-life them, or start supporting them via Lightning setup?
