Is there a way to customize the tabs located on the left side of the screen? For example, I would like the "Code" tab to be shown at the top, instead of the bottom in the order. Is it possible to remove a tab?

When you select the "Code" tab, there is some options showing on top. PHP, CSS2.1, CSS3.0 etc. Is there a way to remove some of those options from the list and even possible add one? I tried right clicking them but there is no options that change you view.

Thanks in advance for any help.

The tabs are fixed. The only option is that you can choose between My Websites or My Computer to show its content by default when the programme opens.
