I love the idea behind blockly of bringing back structured editors to teach beginners in a way that side-steps the time waste of syntactically malformed code. And also the mix direct manipulation and indirect manipulation via coding. But the drag and click input system seems horrendously inefficient even for novice needs; it's not just super-slow to select the desired building block but also seems very frustrating to re-arrange anything; e.g. I couldn't work out a way to reliably select and move out a sub-block etc. Scratch also doesn't save to some human editable format. Is there some more UI depth that I've missed on my first spin that allows more ergonomic usage?
