Show arrow Custom.css

Hi mauricecruz,

I use Linux OS (Ubuntu) and my browser is Chromium.
I installed the custom css for Chromium, but in my DevTool is not showing arrow, I looked at line 1658 of your css code with the following description "/ * hide / expand arrow point to the right * /".

I commented the following lines of code, to visible:
1662 and 1687 for Mac.

There is a segunta sitação at: "/ * hide / expand arrow point to the right * /", I tamém commented the following line of code:
* 1720 and 1737 for Mac.

But I can not see the arrows of panels css, I would like them to become visible, thank you, it's a great job.
