I downloaded SSMS Tools Pack and the region functionality seems to be a bit quirky. For example, for 2 regions on top of each other, collapsing the top region seems to collapse the bottom region as part of it. Have you noticed this behavior? Also, if I just type:

--#region test

-- some sql

--#endregion

Then the region doesn't seem to get automatically "activated" - ie it doesn't collapse and expand. There seem to be other basic quirks as well. Have you found these regions to be buggy as well - a nice thought but not ready for prime time?

Also, do you know if there is any momentum for SSMS to include built-in regions in an upcoming release? Seems like it would be really nice to have considering Visual Studio has had this functionality for over 10 years?
