Version 2.2.7 of Appointments+ introduced the following addition:
Changed default appointments sorting to "Appointment Date".
This is great. However unfortunately, this also flipped the order of listed appointments when viewing Removed appointments. Which means that on the Removed Appointments tab (/wp-admin/admin.php?page=appointments&type=removed) we're first seeing appointments from years ago, and on the last page we see the latest appointments. This isn't particularly helpful. I recommend the order be flipped to display Removed appointments from newest to oldest by "Appointment Date".
