ER Diagram tables size


Is there a way to set tables size or sth. like auto-fit on ER Diagram couse default tables size is to small (have v- & h-scrollbars to extend the content) & I have to resize all tables to be able to work comfortable.

I am also looking for any workaround/fix for this. ER diagrams get clumsy due to the number tables and their relationships with other tables.
