On my PC three appear down the left hand column and when I click on the ... a window appears listing the other emails.

When I use my 15" laptop this window only shows 1 single email addess at a time and when scrolling up and down using the arrows you miss some emails.

Is there any way to make this window deeper to show more emails ?

Is it possible to have more than 3 email accounts left in the unused space at the bottom of the left hand column ?
