Building Symmetry 1.0.28

Suggestion: 

Make the range for the built-in remover tool adjustable via config setting:

 

"Removal Tool (Def: true)": true,
"Remover Tool Range (Def: X):" 123,

Also, thank you for your quick fixed on the mentioned issues. We really appreciate. 

Please can you fix this error
