title: MySQL Workbench auto increment disabled
body: <p>I am using Workbench version 6.3.5 Community and this is GUI question only.</p>
  
  <p>When creating a new table auto increment check-box is disabled.<br>
  Is it a bug or I need to enable this some how in options?<br>
  And how to set start value and step for auto increment in GUI when creating a table?</p>
