Accidentally pressed undo to go back from the relationship list: I was looking for an arrow back and that’s the only one in the UI. Same as for the relationship list, i miss a way to go back to the list of data models, here pressing undo is even more natural .

I don’t feel too strongly about priority here, you need to use the tool in a pretty absent-minded way (as I was) for this to happen.

I would advise doing something about it unless it's too expensive though: it is a pretty glaring dead-end in navigation, and it can be really frustrating if someone truly ends up pressing undo and doesn’t notice losing changes.|
