Component name "Spectacles" Utility - Seen in Chris Mackey Video

Hello everyone! If your a patreon member and watch video " 2 - Building a Simple Single-Zone Energy Model Using Masses2Zones" of the Fundamentals of Energy Modeling with Honeybee video series, Chris Mackey has a utility for showing the names of the components called spectacles. It is not the TT Toolbox version but something different.

Does anyone know where to find this?



Thank you very much!!!
