We need some sort of database visualization.
My suggestion is to create another tab in main view. Within it one can select tables he wants to observe, and main view in which tables and connections between them are shown. It should be updated dynamically whenever table layouts are changed(table removed, modified).
This is just a concept by now, I'll provide sketches.
Help is really wanted. If anyone is interested in this - let me know, we'll create new project in canban cards and a team for it, create issues and assign people to them. I can provide information you might need to know, and we can estimate our efforts and see when we can make this stuff ready2go.
