Gmail's new compose window is hated
When you click on compose in Gmail (for computers) it now displays a window in one corner.
Also, once you've entered the recipient and subject, those fields are no longer labeled.
Most people hate this change, although you can get out of it. They shouldn't change something so that it's the default, especially when it was okay before.

I also hate it when a software company describes something as "an experience."
