I would like to add custom folders to a Sql Server Management Studio 2008 solution. Currently only three folders are included: Connections, Queries, and Miscellaneous with no easy way to add or customize this folder layout.
As far as I recall, you cannot do this, unfortunately. At least not with any "normal" documented methods....
I once even tried to manually edit the resulting *.ssmssqlproj file (it's basically a XML-based Visual Studio solution file, after all), but if I recall correctly, even those folders added manually into the proj file were "killed" at next startup and removed.
The whole solution stuff in SSMS is really majorly lacking right now - which is a bit funny since it's really based on the Visual Studio code base, which can handle lots of scenarios in its solutions......
