my blog post on tools4revit, Smart Browser® is a free Autodesk® Revit® add-on for speedy Revit family searches in external libraries.
Smart Browser usages
Locate Revit families on your computer/server/clouds; itemize and evaluate Revit families what are internal to your current project; review Revit family in 2D and 3D views before inserting into the project; drag and drop elements into Revit projects; share, sell or buy Revit families.
There's a nicely descriptive tutorial on Smart Browser by Benjamin Malone on the BIMopedia website.
This free add-in may be downloaded from the Smart Browser website.
