Same for us here.
It would help a lot to use different colors for tables, which are
- for temporary test purposes
- to distinguish between transformation and export
- …
Even better would be the possibility to use differenrt colours on actions, too.
For example: I often add a filter action to reduce the amount of records of an imported file for testing reason. It would make it much easier to colorize the actions, which have to be deleted (or deactivated) after completing the test.
