OP here. Yeah, I was definitely not aiming for a full IDE here (obviously). It more like a playground environment. Something like CodePen for VR with a focus on the live-coding experience.

Using this app is comfortable but VR will definitely need higher resolutions for anything more serious. It's not too far in the future though. If things go well, I expect VR will be the driving force behind ultra-high-density 5" screens in the next few years. Or some entirely new display tech (retinal projectors?) will replace it.
