Problem with configuring PhpStorm for Typescript

I'm trying to give typescript a shot in PhpStorm for the first time so I'm following the installation steps mentioned in PhpStorm's documentation:

1. Make sure the JavaScript Support and Node.js plugins are enabled. The plugins are bundled with PhpStorm and activated by default. If they are not, enable the plugins.
2. Download and install the Node.js framework.
3. Configure the Node.js interpreter in PhpStorm:
   1. Click on the main toolbar.
   2. On the Node.js page that opens, specify the location of the desired Node.js interpreter.

First of all, the NodeJs plugin was not installed so I had to isntall it from repository.
For the second step, I've already installed NodeJs on my computer so I skipped it. My NodeJs version is 0.10.26.
So I went on to the thrid step where I faced a strange problem. I couldn't find the icon anywhere in main toolbar. So I opened the `Customize Menus and Toolbars..` window and there I found the item `Node.js and NPM` next to `Settings..` item with no icon! Then I thought the reason for it not being shown is because it has no icon to show. So I gave it an icon (a 16*16 png) and now in `Customize Menus and Toolbars..` window it comes with an appropriate icon. But yet when I close `Customize Menus and Toolbars..` window, it is not shown in main toolbar. Or at least not all the time! I mean the nodejs icon comes and goes as if it's playing hide and seek with me. It's so hard to catch the little ba**** but even when I do, it's no use, clicking on it won't open anything!

So what's going on? Why am I having so much trouble following the instructions?

BTW, I'm using Ubuntu 12.04 and java:

java -version
java version "1.7.0_06-ea"
Java(TM) SE Runtime Environment (build 1.7.0_06-ea-b16)
Java HotSpot(TM) 64-Bit Server VM (build 23.2-b07, mixed mode)
