CP Field Inspect (formerly CP Field Links, in Craft 2) is a tiny utility plugin making content modelling a little bit easier in Craft.
Did you forget a field handle? Mouse over the cogwheel next to the field title, and CP Field Inspect will tell you.
Need to adjust some field settings? Click the cogwheel; CP Field Inspect will redirect you to the relevant field's settings page – and back to the content when you're done.
Additionally, CP Field Inspect will add a link in your element edit forms to manage source settings (e.g. entry type, category group) in the same manner.
Note that CP Field Inspect will only be active for admin users.
This plugin will be free forever.
To install this plugin, search for its package name on the Plugin Store and click “Install”.
