1.Added a new menu group "Select menu group" .Add multiple related selection commands.
2.Add undo/redo functions(Default shortcut key Ctrl + Z / Ctrl + Y,Of course, you can also customize shortcut keys).
The plug-in supports the undo and redo functions of all atoms in the scene(Delete, add, position, rotate).
But the function is still limited.I'm developing a menu item to undo and redo for a single atom.In addition, I'm letting Undo Redo support more projects.
