CTRI Tweaks is a collection of small tweaks that are too minor or specific to CTRI to justify a published EM. When a feature or group of features is sufficently mature we spin that off into its own EM.
This module isn't available via the REDCap EM repo, you'll need to drop it directly in your modules folder (i.e. redcap/modules/ctri_tweaks_v1.0.0).
