Ability to increase/decrease size of editor window

[Naman_Mittal]

Hi All, It would be great to give the flexibility to increase/decrease the width & height of the code window for writing SQL code in the "Source Step". Right now it is so small I could sometimes read only 2-3 lines and have to scroll a lot while the actual screen size is so big compare to this window, it would be more productive for us. Thanks!
