I came here to post this topic haha. Really wonderful design tools you've made. Making games is supposed to be fun too, you're really onto something here on the asset side of things that I fear you aren't considering. If every level design plugin was development in the way your game was, well, I mean this may sound exaggerated...but I truly feel a suite of plugins in this style would revolutionize and set new quality standards for game development. Think about it!
In the end, good work and thank you for creating this inspirational piece of software!
