In Revit 2014, you can select multiple detail items or imported raster images, and use the Send to Back, Send Backward, Bring to Front, or Bring Forward tools to move them all in one operation.

The second enhancement enables you to use the align tool on a divided surface in the Conceptual Massing Environment. You can align the UV grids on a planar divided surface by using a straight edge of the surface as a reference, or an external reference. This method enables you to rotate the grid to be aligned to the edges you select.

Also now you can tag the material of building elements in 3D view. Once you lock the 3D view, you can then begin tagging the materials.

 In Summary:   The enhanced productivity tools improve control over elements in your project and construction documents, and help you to better visualize design intent.
