titlecasesuggestions
Sets article titles to have recommended title casing when an article title is filled in.
The author can uncheck a box to regain control of capitalization. Currently, there is no button to undo the automatic capitalization that was done.
This uses a third-party service - https://titlecaseconverter.com/ - that you need to sign up for and add a credit card (100 API usages a month are free) - https://rapidapi.com/Matt11/api/title-case-converter
Currently there is no settings interface, to provide the API key add it to your settings.local.php file:
$config['titlecasesuggestions.settings']['rapidapi_key'] = 'Your RapidAPI TitleCaseConverter Application Key';
Would be very interested in swapping out the 3rd-party service for an open source free/libre software alternative, but looks like someone would have to write that.
Bonus feature: Copies the title to an "index title" used to give a shorter version of the title, if this field exists. If others are interested in this feature we can make it configurable, please open an issue.
