Use case or problem
In the future I can imagine some bases getting pretty large with many columns (property-fields), which will cause them to scroll horizontally.
In those cases it would be nice to be able to pin columns so that they stay visible no matter how far you have scrolled away horizontally.
That way the filename or other field could always be visible and provide valuable context.
I imagine this to be very similar to the typical Excel/Spreadsheet-Functionality where you can also pin Columns/Rows to always stay visible
