Good it works out for you, the cfg is my name of the User Interface, so guess i should remember to not use that word on it
You will find the load from and save in, in Customize/ Options.
After you have made some change you like to keep in how the worplace look like when it comes to where you place the different Tools to your like etc., go there and in the Save in section just overwrite the name with something that make sence for you and you will see that it turns up on the left side aswell, then you can select and re load it if needed at a later time.
Next time TC will ask you if you want to change it and then you click ok if you want to.
