Thanks. Will be handy.

However..."titlecase" simply capitalises every word.
Title case normally leaves some words:

Articles (a, an, the)
Conjunctions (e.g., and, but, or)
Prepositions (e.g., on, in, with)

in lower case (except at beginning).

If that seems too much hassle, maybe just rename your option "Capitalise".

See e.g :

http://blog.apastyle.org/apastyle/20...apa-style.html
https://saijogeorge.com/title-case-converter/ seems accurate

PS -- also found some anomalies: it will convert
"CHAPTER XVII–FINDS PRINT OF MAN’S FOOT ON THE SAND" to
"Chapter Xvii—Finds Print Of Man’S Foot On The Sand"
which I need to make several manual changes to make it true title case:
"Chapter XVII—Finds Print of Man’s Foot on the Sand".
The capital after an apostrophe is wrong even for simple capitalising.
