How can I see the folder size on dropbox.com

The long waited request for the ability to see folder sizes on web (dropbox.com) is now live! 

To enable it

• Open dropbox.com and go to 'files'
• On your file/folder view, click on the arrow-down ‘Modified’ and select ‘Size’
• Click on the arrow-down ‘Modified’ and select ‘Size’
• Then click on the folder you want to calculate the size
• Click on ‘Calculate size” (on the right-hand side, last link) 

Voilá:

If you select more than one folder the 'Calculate size' option will not appear. The 'Calculate size' option will only appear if the 'Size' column is displayed.
