It would be enormously helpful to have these options added to "modify columns", the column headings, filter by when searching for contact(s). And update Job Title within contact details. 1. Modify Columns: have ability to freeze Modified Column Headings selected throughout when scrolling down the page. Very Challenging! 2. Selecting column header to sort. i.e., expand sort selection beyond email, first and last name to alpha sort with the other modified columns selected. 3. Searching/filtering Contacts with the drop-down options. Add tags please! 4. Add Tags to 'modify column' selections. 5. Contact Details. Job Title-increase number of characters allowed. In our industry, titles frequently require another 8 letters or so. Thanks!
