I'm coming from MS Access world (building apps) and there you could build an event when the user clicks or double clicks the specific column in the list view (the specific cell so to speak). In K2 there are only two list view events possible - the click and the double click event for the whole item (row). This is quite limited. If you want to make an amendment to specific cell under certain conditions (and you don't want your users to edit the whole row), or open different subviews for different columns or do any other actions related to the data in specific column (for example - by double clicking the ID cell you could delete the whole row from SO (upon confirmation of course), while by double clicking the user cell you could only send a notification to that specific user), the additional column click or double click events would be very useful (alternatives are not that great tbh, they mean more work and are not that user friendly). Check my pic from MS Access -> by double clicking on different cells you can trigger different column events.
