Sorry but your further request for things like maintaining roman numerals and acronyms in allcaps within titlecased headings is a straight no.

The reason I'm not going to fulfill that request is because I recently tested your heading shown here:

CHAPTER XVII–FINDS PRINT OF MAN’S FOOT ON THE SAND

...using four online titlecase converters and they all gave the following conversion:

Chapter Xvii – Finds print of Man's Foot on the Sand

Your roman numeral request really requires two things that are difficult to achieve:

* Convert the heading to "proper" titlecase

* But also maintain differing roman numeral combinations or acronyms as allcaps in all titlecased headings.

And that's why I regard this request as completely unrealistic.

Regarding acronyms -- do you really think it's reasonable to expect this plugin to be able to guarantee that all English acronyms used by all indie authors be maintained as a list on this plugin? Get real !!

So for acronyms or allcap abbreviations as well as roman numerals as allcaps within titlecase headings are both a no I'm afraid. You also appear to be using en dash or em dash in your Logical TOC titles which is also quite dangerous(UNICODE not ASCII ???).
