Roughly Enough Professions (REP) - REI Extension
This mod significantly expands the capabilities of the popular REI (Roughly Enough Items) mod, adding convenient functionality for working with villager professions. Now you can easily determine which specific worktables are required for each villager profession.
To use the new feature, simply hover over an emerald or villager spawn egg and press the usage view key (default - U). A complete list of all available villager professions will appear on the screen. If you need to know which specific mod added a particular profession, just hold the Shift key - in this case, the mod identifier will be displayed before the profession name.
If you prefer to use JEI instead of REI, a similar mod called Just Enough Professions (JEP) is available for you.
