Glad you are finding interesting. 
Right - forgot to mention in the instructions that you should toggle a few settings in the Unreal Editor to get a better experience:
In the Unreal Editor menu select Edit -> Editor Preferencesā¦
Then in that dialog make sure that General -> Miscellaneous -> Performance -> Use Less CPU When In Background ] is unchecked.
Also make sure in the same dialog that Level Editor -> Sound -> Allow Background Audio is enabled.
This assumes that all the other settings are default. There are lots of other Unreal Editor settings - I recommend exploring around in there and see what else looks interesting to tinker with.
We normally hook up the IDE to the World Editor so that tilde ~ or Ctrl+~ toggles the Skookum IDE just like many game consoles. We will be hooking up into the Unreal Editor with the plug-in in the near future.
You can get the best power and productivity from the scripting system and the editor having greater integration.
Being able to edit scripts on a separate monitor from the game / editor is totally awesome. It is especially nice when doing stepwise debugging.
If you look at the typical workstation setups on other projects everyone has two monitors. It still works with just one monitor of course.
