Schema Browser is a XRMToolbox plugin with origins back to a console app written in desperation by an experienced developer trying to wrap his hands around what would eventually be called DataVerse. The original console app had caching, code templating and record fetching, but was based on knowing the keys to use (old vi users die hard).
Since moving to a XRMToolbox plugin, Schema Browser has grown and changed into the tool you see today. After using it myself in daily work, I’ve decided to put it out in the wild for others to use.
