Inside the Web-based TNEW interface, there are Rich Text Editors for different fields. Inside them there are formatting options for settings like headings, fonts, font-sizes, etc.

It would be very handy if we could define additional formatting options to the format dropdown of the RTE, as we've had issues where a user has written inline styling to many of the Rich Text elements. If we could define some basic format options for accented text or buttons, that would open up many safe options for typography customisations within the TNEW Rich Text Editors, without the need to rely on inline CSS. The Umbraco CMS allows us to customise these options, for example.

Looks like TNEW Web is using CKEditor. Some instructions on how to get custom formatting options going are here: https://ckeditor.com/docs/ckeditor4/latest/features/format.html
