Here are functions: 1 - Filtering by lists of replacement and new material 2 - The ability to select materials with a pipette 3 - Work globally or only on selected objects 4 - The ability to isolate the selected by making it unique. At the same time, the connection between the copies of the components inside the selection remains 5 - Rubber web dialog 6 - When selecting the "Unique" mode, the object isolation operation is displayed withe a progress bar Many thanks to authors of GMC and MT.
