Erase all email at once
There is no function to erase all emails from trash at once. When you open the trash, missive loads first 50 mails. If there is more then 50 mails, you have to scroll down to to bottom of the list and wait for next emails to load. Imagine you are putting 1000 mails to trash everyday. You need the function to erase all 1000 mails at once.
