Hello,
Like a few other people, I'm not a fan of the new mail interface. I thought it might help to share a few concerns. And perhaps others can chime in with some ideas, too.
My main issues are:
1. The far left menu (mail, calendar, tasks) takes up a lot of space. This space could be used to make the folders section much wider. The folders section is too small and narrow.
2. The drop down menu with email addresses at the bottom is
HORRIBLE. For people with multiple accounts it's hard to scroll down and see what accounts have new mail. The font is too small. For some addresses the email address is longer than width of the provided space. There should be a MUCH easier way to see all our email accounts at a glance. As things are now it's really hard to see what accounts have new mail, and easily toggle between them.
Hope you'll incorporate these suggestions. Zoho mail is great, but this new UX is a big step backwards.
