I am using SSDT Dec 2012 release with VS2010.
I find it very inefficient, time consuming and difficult to find an object (table, sp, etc) in the SQL Server Object Explorer when working in the connected mode and on a large database. Since I rely on the Red Gate SQL Search in the SSMS I cannot switch to VS2010 Database Connected development.
Similarly, when I try to find an object file in the SQL Project there is no user friendly and interactive search to quickly find an object in the project. Existing Find and Find In Text helps, but it does not clearly outline the object files. Instead, the file names are part of the text search results and not that easy to spot.
