You app skips way down to read emails immediately after reading the first unread email so I have to tab back up to top to get the next unread
email. I like the app but cannot buy it under these circumstances.
If your most recent mail Unread are at the bottom it’s a sorting issue mine are top to bottom.
Just play with the mail sorting order 
loll
Forgot to mention to scroll down the email is [space] but stop at the bottom unlike outlook which jump to the next email below.
Previous mail: [CTRL]+<
Next mail: [CTRL]+>
Those are the shorcut.
