I'm building a new prototype, working title: GLUI

It's an attempt to enable creating complex configurations and scripts while avoiding the problems and limitations of configuration languages, scripting languages and UIs

Here's the introduction video: https://www.youtube.com/watch?v=9PJ9UjX-Odk

If you find it too long you may want to use the Chapters feature to jump to sections that interest to you.

The introduction and motivation may be useful to get an overview.

For a quick take on the powerful aspects of the prototype you may want to jump to 14:34 where I reuse a connection config in 3 places by linking to it
and the derive a new configuration from it by using the derive feature.

You want to try it? sure, here it is, just remember it's the first version:

Please let me know what you think, if you would like to know more contact me and we can get into the details and/or vision for this.
