Goto Type/Database Object
Resharper, a popular addon for visual studio has a nifty feature where you can hit ctrl+t to open a compact search window where you can type part of a type name, and a list of clickable suggestions is presented as you type.
It would be quite handy to have something similar for Management Studio.
Clicking any of the matches could open a new query window with an ALTER statement prepared.
I would suggest it be a small dockable window and default behavior for clicking on it would be go to the object in object explorer with a right click context menu for more options (like a window with alter/create). This functionality already exists in SQL Hunting Dog but it was last updated on github in 2017 https://github.com/bugzinga/sql-hunting-dog
