Most of the column lists (View | Columns, editing tooltips, choosing visible columns in the grid, selecting columns to be shown on the correlation plot, selecting features when building a model, etc) now support searching.
When a column selection popup is open (for instance, when you are selecting a column to show on a scatter plot axis), simply start typing, and the search box appears on the top.
New “Plots” context pane automatically visualized selected columns. For instance, if you have two numerical columns selected, you’ll see a scatter plot. One categorical and one numerical - bar chart and box plot. This can save you plenty of clicks when exploring your data.
