Add a case-insensitive find & replace

While testing the latest version of the Node Find Replace module, I noticed that not all the changes I expected were being made. Later on, I realized this was because the search was case sensitive (which I hadn't realized till then, despite it being stated on the module's admin page). Would it be possible to have an option to make the search case-insensitive for cases in which you want to replace both lowercase & titlecase phrases, for example?
