This sample shows some sample plugins implementations. Things to note:
		
			- In the toolbar, you will find sample "Find" and "Replace" plugins that do exactly
				the same thing that the built in ones do. It just shows how to do that with a custom
				implementation. Use the green toolbar buttons the test then. 
- There is also another sample plugin that is available in the package: the "Placeholder"
				command (use the yellow icon). 
- It also shows a custom context menu option when right cliking on images (insert
				a smiley to test it).
