Feature summary (what you would like to be able to do and where):
Currently, the Display Title feature seems to allow different letter case only for the first letter.
It would be helpful if it allowed also a capitalization change at different position.
Use case(s) (list the steps that you performed to discover that problem, and describe the actual underlying problem which you want to solve. Do not describe only a solution):
E.g. organic chemistry nomenclature uses various prefixes (descriptors). If capitalization of the whole name is needed (mainly at beginnings of sentences; in English language, capitalization seems to to be preferred also e.g. at some indexes/listings), the prefixes are to be untouched, and the change occurs at the first ~word.
Examples of proper capitalization (incl. other formatting) of chemical names:
(Note: other additional formatting needed in some cases, italics, is not applied, as the corresponding Retext syntax does not work for some reason.)
- 2-methylpentane → 2-Methylpentane
- tert-butyl → tert-Butyl
- N,N-dimethylaniline → N,N-Dimethylaniline
Benefits (why should this be implemented?):
Current Display Title feature is a benefit for articles of somehow case-sensitive topics like UN*X command names, e.g. cat (Unix).
This additional feature would be a benefit for e.g. already mentioned organic chemistry compound names to have the title properly formatted, without having to have that specific capitalization in the article name itself (thus sort of breaking WP:NCCAPS).
