Local View Manager

Simple and intuitive addon to complement functionality, as Blender does not add, undo or redo into Local View.

Features:

• Toggle (alphanumerical /), remove (alt/), add (shift/) and recover (ctrl/) to Local View from the Outliner and Viewport;
• Operations from the Outliner affect the first or, if many, the Primary Viewport only;
• Recover memory only writes from the extension’s operands, so Blender’s defaults do not get registered to compose the final Local View state. Extension’s shortcuts are first in keymaps to override Blender’s, except for (alt) numpad/ that remain as default;
• Temporary collections linked with per Local View objects to also isolate them in the Outliner. Specially useful when working locally with apart objects in the list;
• More explicit indicator, as top-right red button, to aid Local View workflow;

Found in [n-pannel > View] [Viewport > View menu] [Outliner context menus].

Still figuring out how to carry the Primary label with the Viewport when moving it in the workspace. LVM will reassign automatically. To be sure where you want to send commands from the Outliner, reset your Primary Viewport manually.
