Improves default “Local View” (isolate object) so that it can also isolate
faces, verts, and edges in Edit Mode, using the same button.
Why ?
If you don't like jumping from H, Shif+H, Alt+H to isolate objects,
or that Alt+H changes your selection.... You might be interested in this extension.
It isolates objects or elements with single button, more like Isolate object in Maya.
