Duplicate antagonistic features

[Isaaclhy00]

each pair of "list /e" and "list /e", "showonly" and "hideonly" seems to achieve the same purpose of filtering the list to only display certain columns. Although it is thoughtful to include such features (in case users want to only show only column and do not wish to type "hideonly x x x x" or if users only wish to hide one column and do not wish to type "showonly x x x x x"), the idea of only displaying certain columns may be unnecessary as the list is already in table form and the columns are not overtly confusing to track. An alternative would be to add buttons on the
top of the table similar to the "Residents" and "Bookings" buttons, each attribute of a resident can be a button and can be pressed or un-pressed to select if the column is to be shown in the list below.
