Amount of space above white box that contains actual emails eats up too much space. It looks nice but Yahoo Mail | Search Mail etc eats up too much space. I have a 17" screen and I want to scream!

Action Icon Tool bar is too large for the size of the icons and eats up way more space. May look nice but shrink it and put a border around it. Yes, I see it is the same size as the ad space above emails. Shrink that too. Sorry, but keeping me is way more important than the size of the space around the ad.

The bar with the types of emails is totally unnecessary. Put it as a drop down on the left menu bar.

I detest light or dark only. SUPER ******* the eyes of us OLD people.

MOST IMPORTANT, having to mouseover the address area to see what the FROM ADDRESS is DANGEROUS for scams & spam. MOST will never figure it out leaving them vulnerable. Sender's Email Address - You don't have to open the message to see the sender's email address. Just hover over the sender's name from your Inbox. BAD BAD BAD IDEA! Just not safe.

Stars from the emails list is too small and needs to return to the left side.
