Use case or problem
Backlinks are duplicated when using the “Backlink in document” option.
Proposed solution
A toggle option to hide backlinks from the sidebar in the “Backlinks” core plugin settings.
You can close the Backlinks tab, but it will come back if you close and reopen the vault.
Another option, for now, is moving it off to the right of those icons or into a different tab group so that it’s not in your way.
I believe a dedicated fix like a toggle switch would be better. Otherwise it just bloats up the UI with an unclosable and redundant section.
