Adding the possibility to freeze / unfreeze columns from a left click on the column header would provide more visibility to users and a faster access to this feature.
Eventually the possibility to customize the headers' font for the frozen columns and/or have a custom vertical line (width, colour, dashed/dotted/plain) to be give a "heads up" on which columns frozen (set from the visualization's properties).
See attached modified screenshot.
Thank you for your consideration.
Kind regards,
