When I right-click on a suspect email, a menu appears next to the pointer. The options are too close together and are prone to a mis-click that will inadvertently send legit emails to hell.
The options should be resorted and spaced further apart. The order of actions should be reset to separate blacklisting and friending.
Many are now using tiny laptops/netbooks that are difficult to use in either viewing the screen or doing precision pointing with the touchpad.
