Hello, 

I am looking for a way to make the sheet in the form-view wider so that less place is take by the chatter box, and more place is available for the form. 

I found in the enterprise/web_enterprise/static/src/scss/secondary_variables.scss that you can change the following value:

$o-form-sheet-min-width: 1200px !default;

This does moves the chatter to the right, but the sheet on the left stays as big. The margins on the side get bigger. 

So how can I make the workable form wider? 
The frustrating part is that I actually knew how to do it, but I forgot and I can't find it anymore. 
Thanks for the help pointing me to the solution!
