[fixed] Ticket #3978 - reference sketch dimensions lose their reference mode

But then you can select the dimension and use the corresponding toolbar button to turn it into driving.

Yes, I can. However, doing double click is handy.

I am opposed to "magic". If I open a reference dimension and then press OK without changing it, I did not change it so why should it automatically be changed? A good UI should only do what the user tells it should do.

Yup. Magic is not good. Automatic changes helping the user avoid further UI iterations and clearly showing to him what is to be expected are not magic though. That it was I was mentioning complementing the wanted behaviour with additional GUI elements not to surprise the user.

Thinking about how exactly, a checkbox showing the state, came to my mind.

IMHO, the best solution would be that there is a toggle button in the constraint editing box that both indicates current state (driven or driving) and allows the user to switch mode.

EDIT : another acceptable solution would be that a driven(reference) dimension always displays an editing value of something like "#ref". If the user change it for a number, then it become driving.

Yup, I came to the same conclusion of the need to show the state.
