Description
If there is a lot of code in between, it can be hard to tell what an // endregion marker refers to. One way is to copy paste the label but then you would need to keep it in sync whenever you update it (think about c++ namespace, ifdef, etc. ending comment markers)
Proposal: Add an inlay hint after // endregion markers that display the label.
Alternative: Provide goto definition for // endregion markers
