Comment/Uncomment selection

SSMS has standard feature allowing to comment selected text, however, it uses "--" syntax, making impossible to insert comments within the line.
SSMSBoost has added smart /*comment selection*/ feature, which does exactly what developers expect it to do: it puts /**/ marks around the selected text:

Additionally, this feature can be used to remove comments, when selection exactly matches comment bounds (works with both /**/ and -- syntax):
