Windows 11 Feature Requests - Regression

Hi,

I am on windows 11 since 2 weeks. It's great but I 2 very useful features have disappeared.

First one : 

When you want to save an image on your desk, you could drag it to the right corner, make the desk appear and drop it.
You cannot do it anymore

Second one : 
When you want to upload files online (ie: join pdf on an email), you cannot drag the file from local space to your browser !
This is really boring to find files from the browser when you have to habit to drop them from local !

Where can I suggest adding it to windows 11 ?
Have a nice day
