Please stop changing things without options to keep old or change the view. This new view is atrocious. Who really thinks they did someone some good here?
Add a resize cursor to shrink the History column which is way to wide. The speed dial column is narrow. The layout should be user configurable. This new look is not an improvement. Please revisit the decision to mess things up and make so many unhappy Teams users.
Atrocious is a good description, not a good layout and the user should be able to choose how wide the columns are since this is being forced on us with no input. MS should try and make the customer experience better.
