Join recipe is one the most visual recipes that I use in Dataiku. This is a request for a feature addition in join recipe. I usually deal with datasets with number of columns more than 100. For column selection in the join recipe, I need to scroll down the page to select the required columns from datasets in question, which sometimes is a cumbersome task to find out one column or a list of columns through scrolling.
Thus, if we could have a search option in the column selection UI, it would be very helpful. I believe it will certainly enhance user experience to working with visual recipe like join recipe. For reference, I have added a screenshot herewith.
