I noticed a minor bug in the layout of task details page. It's minor, but I think in such great product there should not be such bugs.

Browser and OS: Ubuntu 14.04, Chrome 56

Steps to reproduce:

1. Open Activities page

2. Select any Task and open Task details page

You will see the horizontal scroll in the browser. 

Possible solution: crmcontemporary.css, selector .tb_newmenu - remove padding-left.

I'm including the screenshot, hope it helps.
