Given a long list of tables in a DB in the SSMS Object Explorer:
dbo.a
dbo.b
dbo.c
...
dbo.z
Key search, e.g. press "z" to get focus on dbo.z doesn't work here, because the search considers the first letter of the prefix, not the one of the table name. I always end up scrolling the list with the mouse to get to the table I want. Doesn't sound like big problem, but when you work a lot with SSMS like me, you learn to appreciate every saved second 🙂
