New widget - add attributes

[borondics]

What's your use case?

We are using attributes more and more to carry information about the dataset. However, it doesn't seem possible to add new attributes from inside Orange. This becomes a problem if the necessary fields are not populated for any reason.

What's your proposed solution?

It would be great to have an Add attribute widget, where the user would specify the name of the attribute and then the value (string).

Are there any alternative solutions?

One can edit files but in that case they would need to conform to the individual file structure.
