Depending on the features you are adding or changing to ‘fine tune’, you may want to give the following linked pp a try. It has a couple of features for hobby and small business operations, and all features are easy to setup, maintain, or extend via use of Sheetcam’s Custom Options and Custom Tool and Operations parameters.
I’ve helped a couple of folks with JDG tables by using this pp, and it was just updated it with the latest fix.
