In Visual Studio\'s Server Explorer window there\'s a very nice feature that lets you see the DB objects grouped by schema:
It turns this object tree:
You can try as follows in SSMS: Tables > Filter > Filter Settings
There you are able to filter by schema...
If you want a free tool, SSMS Schema Folders (GitHub repo) is your solution. It does the job beautifully.
I love the idea of grouping by schema.
SQL Treeo SSMS Addin is an inexpensive tool that allows you to create your own table structure in the Object Explorer.
