Add sort column headers - like Outlook and Mac.Mail
I would love the ability to expand the width of the email folder view to show additional columns of data, such as sender, subject, date, size, attachment etc.
I would then love to have 'sort headers' like Outlook and Mac.Mail have - to easily sort by whatever column we chose.
This would dramatically simplify the ability to find and sort emails, compared to the current method.
This might not be desired by all users - so perhaps 'column headers' could be made as a display setting in the preferences?
This is the biggest feature I miss from other email clients and something I I wish was implemented
