Hello, Patterns!
Thanks for making it convenient to use.
However, I would also like to change individual names.
That is, the function of the original "Renamer".
Couldn't it be possible to add a separate button to the GUI only for the mass change function?
This will allow we to use both functions simultaneously in the same GUI.
thank you :)

That's a good idea, I'll have a look and see what I can do.
(I'm not really a modder and my familiarity with the Factorio API is cursory at best, but it wouldn't hurt to try!)
