No back or save button when configuring a facet

[evertrol]

In the screen for configuring a facet, there is no "back" button or similar to go back to the analysis screen: one has to click on "Analyze" in the menu again (note: the browser back button also works).
This works, but may be slightly confusing, especially since there is also no "save" button or similar in the facet configuration screen. This could leave the impression that changes to the facet are not saved.
Similar for the "configure partition" screen when clicking on an item in a graph config screen.

This pattern has become more common over the years (automatic saves behind the screens; select relevant item to move there, instead of using a "back" option), so this is probably a minor issue.
But it took me a few seconds searching for a "save" or "back" button, before deciding to click "Analyze" again to go back. And I was only reassured it worked (and didn't discard my changes), once I saw the variable name had properly changed in the analysis screen as well.

One option could be to provide some clearer feedback that a facet has indeed correctly been changed, for example by a fading "saved" message next the aspect that was just changed.
So if I add e.g. a unit, then hit tab or click elsewhere to move out of that field in the form, a "saved" message could appear behind the newly added unit.
This only partly works though, since if I add a new unit but do not leave that field, but instead click "Analyze", it will also move me back to the analysis screen, with the new unit saved: there was no time to show a "saved" message.
