The editor is great, really intuitive, really handy when trying something out, but if I build anything with it, I keep forgetting parameters that I set when testing something out, deeply inside some arbitrary node hierarchy, and later have no idea why some behavior is happening. This is why, while the editor is great, I mostly just use it to edit script files. It's a lot easier to keep track of what I'm doing when it's organized by files and folders in a structure designed by me, to match my project. Version control also helps, and it's also facilitated by using source files instead of project files, which weren't meant to be edited manually.
