All,

In trunk there is now one example of editing values in the displaystabs: you can edit the value of attribute of source and citation (so SrcAttribute displaytab).

Code do change a textfield in a tab to allow this is simple, see changes done in
http://sourceforge.net/p/gramps/code/22437

So, what other fields to enable like this? Post on http://www.gramps-project.org/bugs/view.php?id=6780 what you would like to see editable in the tabs.

Some remarks:
1/ I don't made the srcattribute type itself editable in the displaytab. I think this is not something that normally will change after first creation. If people have good reasoning to allow other types on other displaytabs, I can add a generic mechanism to allow editable comboxes in displaytabs

2/ I added private column to displaytab (http://www.gramps-project.org/bugs/view.php?id=6780), but this is not editable. As privacy is an important thing we don't want people changing by accidently clicking somewhere, I did not do this.

3/Don't suggest to make complicated fields editable in displaytabs. So not eg Name of a person, as that is a compound field.
