This is really interesting. I happen to dislike GUIs wherever it comes to any kind of software development. CLIs are just more programmatic, and I happen to be comfortable with programming. I've thought quite a bit about this while working on Pragma [0]. I think GUIs offered by BaaS (e.g. Firebase or Hasura) just aren't efficient compared to writing everything in files and using Git and my favorite text editor to work with it.
