in the profile view of data refinery you can look at the various aspect of the data. When a column needs to be removed you have to get to the other tab and you loss the column you want to delete
it would save a lot os time in data cleansing/prep to have basic command in the profile view/tab.
the typical example is a column that has only empty or null value or a single value. This column is not useful for any analysis.
In the profile view it would also be useful to have the list of unique element and its count in this column. To see if the column is useful for an analysis later on.
