Muzzleflash released version 3 of his Simple Developer Console on the BI forums.
This is another debug console. It supports saving and loading snippets and you can specify where to run the code.

Changelog:

• On kju's tip I've made it so you don't need to do anything to activate it anymore (other than activate the addon of course).
  
• Minor fixes
  
• There was a bug that meant it didn't remember snippets across mission loads; this is fixed now.
