Sorry for the late reply (www.ads-software.com does not notify about support requests).
From the plugin description:
iG:Syntax Hiliter allows you to post source code to your site with syntax highlighting and formatting (as seen in code editors, IDEs). You can paste the code as is from your code editor or IDE and this plugin will take care of all the code colouring and preserve your formatting.
So it wont show any toolbar or anything else when you’re writing your post. What it does is when you post source code (Java, PHP, HTML, etc) for display in your post, it displays that on your website/blog in a neat beautiful way. You would need to use relevant tags to beautify your source code though. More info on that here.
You can see the plugin in action on this blog post in which all code examples have been presented in a neat way by this plugin.
This plugin is basically meant for software engineers & web developers/designers who post source code to share with others. If you don’t write code then this plugin is most likely not meant for you. ??
