Modified the plugin a little. - 1.0.2
Changed the menu.
Added a new function - Multi-Selection Isolate: isolates objects that are selected in different contexts (located at different levels of the hierarchy). Works slowly when there are a lot of such objects But sometimes it can select and isolate something that the usual function cannot.
