- Endpoints. Currently, the endpoints ENDPOINTS_TO_REMOVE and GROUPS_TO_REMOVE can include comma separate lists of endpoints and groups to disable as example ENDPOINTS_TO_REMOVE=img-to-pdf,remove-pages would disable both image-to-pdf and remove pages, GROUPS_TO_REMOVE=LibreOffice Would disable all things that use LibreOffice.

- customStaticFilePath. Customise static files such as the app logo by placing files in the /customFiles/static/ directory. An example of customising app logo is placing a /customFiles/static/favicon.svg to override current SVG. This can be used to change any images/icons/css/fonts/js etc in Stirling-PDF
