It would be useful to be able to temporarily disable a transformation or tab but still be able to run the project. For example, I have a routine that loads from a directory and outputs to SQL server at the end. I currently have a HALT routine to keep it from processing based upon the value of a parameter.
This feature will appear in version 3.8 planned for release in September.
Hint: when you Ctrl+click a transformation EasyMorph executes all transformations up to the clicked one, but not further.
