I'm just getting started with WAB. I have configured a few test apps online and found that I could get pretty far with that interface, but still needed more customization. I recently got access to Beta 3 and set it up on my server. I can see that customizing every aspect locally will take some time. My question is this: Can I configure the bulk of my app online, then download that code so I can do the final adjustments locally? If so, how do I get access to the code generated using the online interface?
