I am very disappointed with the new Yahoo email format. Deleting many emails on the list at a time used to be easy. With the classic version, I would check a box on the left then hold down the shift key to scroll down the email list and click an email further down the list. Just those emails would be checked, then I could delete them all by clicking the trash icon. When I tried it with the new Yahoo mail, it selected many emails that I did NOT select and it put checked boxes in front of them all. That is unusable. This new version is really buggy and I am considering using a gmail account instead.
