I really love the refactoring features, but came across 2 things that might be addressed.

1. when renaming procedure variable and the same variable name is used in other SP that is called using explicit variable assignment, e.g.
   EXEC dbo.otherSp @variable = @variable,
   the other SP variable gets renamed as well
   (e.g. rename
   @variable to @newName creates
   EXEC dbo.otherSp @newName = @newName
   instead of
   EXEC dbo.otherSp @variable = @newName)
   when variable is part of an EXEC command and parameter contains assignment operator, only the variable following an assignment operator should be renamed

2. when leaving table alias as it is and changing the source table for the alias
   if the new table does not contain column names used throughout the procedure,
   inexistent column names get underlined as expected in most cases (selects, joins on...) but not for ROW_NUMBER() OVER (PARTITION BY /ORDER BY) inside OVER block, it seems like it's a valid column name
   if renaming the alias works inside this blocks, so should the intellisense when changing the source of an alias in all places the alias is used

otherwise it's great feature and thank You for it, really helps ;)
