So I tried the lame-o suggestion with the shortcut key. Really useless - when the action is greyed out in the message menus.
The "X" was perfect and was not an issue If i am specifically placing my mouse on the "X" i am intentionally looking to delete. why do I need to confirm delete. history of messages is always there. Simply if it was not broken, then why fix it what is not broken. Feels like a a bigger mouse trap.
The swipe is not even acceptable, But this is HIGH FRICTION - which goes against all of Apples principles.
- Swipe Left with Two fingers ( Sort of more inconvenient/problematic on a mouse )
- Click the Delete,
- Click on the Confirm
Lastly a major point, apparently the designer and even the developer may be out of touch with Fitts's Law
Viola - Formula for Complete Disaster. I preferred the Old Apple Low Friction, form and design.
