Converting message title characters to lowercase + the ability to replace spaces with another character, e.g. an underscore

[mIQ79]

Can you add an additional option in the PDF output file tab to convert the message subject string to lowercase letters and to replace space characters with other characters, e.g. underscore (_)?
The rest works great. Good job!

Thanks for the kudos!
Having substitution rules is something I already have in my head. Upper and lower case conversion is something I have to figure out from a ui setup perspective.
I have to do a major rewrite, however, before I try to cram more into the current old code architecture.
