In subsec Customizer you mention that you did not understand this tool. Is this necessary?
I would prefer if you would compare the tools. In RW section you could focus on why you decided to make a new tool (maybe there are more reasons than you not understanding it?). At the end (in discussion/evaluation) you can focus on the differences between the tools and when your tool should be used and it more applicable.
