We often have to write rules like IF COL1 = value_1 THEN RESULT 1 ELSE IF …
Now we cannot minimize the expression builder window. The button is not available even when the window size is at maximum. We often want to look into the dataset to copy the values that have to go in the expression, so we need to be able to switch between the dataset and the expression builder.
What would even be better is an auto complete in the expression builder so that columns autocomplete and even their possible values.
