Toggle to expand or collapse split notes

Use case or problem

This request is related to the commands split right or split left. To focus better on our active note, I’d like to be able to collapse or expand all split notes on the right / left excluding the active note

Proposed solution

A toggle shortcut to expand / collapse all split notes on the right or left except the active note.

Current workaround (optional)

Some plugins toggle a kind of fullscreen view for active notes, but these are already dated and are buggy. This kind of feature should be better integrated in core Obsidian and not rely on some plugin.

I talked already about this feature in the past, but couldn’t find my post anymore . Also nobody else seems requesting this feature
