For many years I have kept improving this tool.
If you are a modeller or rigger, scene rename is one thing you will never avoid.
Depending on different workflows, the way we group meshes can be very different,
Many mistakes, like spelling mistakes, duplicated names or numbers inside multi groups, could happen.
The idea is to have a library where I can store names and apply them to any mesh with a click.
Less typing, less error.
