First off great program!! I came from Outlook 2013 which couldn’t sync with gmail for it’s life (synchronization errors and kept updating folders… as mess). Overall it is great compared to Outlook mainly because it JUST WORKS.
My biggest complaint is the small menu bar at the top (New, reply, forward, print, delete) since they are commonly used when going through emails. Especially working on a 24" 1920x1200 display, I feel like having the option to move to small tiles (similar to Outlook 2013) would be appreciated since it makes quickly tapping delete/reply etc far faster instead of having to “hone in” on the button.
The capability to “configure” this tool bar is critical to usability. It should allow the user to add / remove icons from the tool bar and specify if they should be “large” or “small”. Currently, it is difficult to find the proper icon, and on a touch screen it’s too easy to hit the wrong one.
