Now that I know how to drag a column from a table to a query, I would like to see the columns in two table at the same time just like I could in SSMS
I suppose you were talking about dragging columns from Object Explorer pane to Editor.
We discussed this internally and do not think we will repeat SSMS approach to display columns (and other objects like triggers etc.) as second level of tables.
We suggest to use Columns bottom pane and Code Completion which is much more easy to use than drag from Object Explorer.
Also you can place any object to Object Details pane and copy any kind of information right from the grid and put it to any place. See my screen attached.
