+1 it would be amazing to have something like that ^^
So, I just discovered how to make tabs and I realized while making a tab for a pairing of my characters, there was no option to make the tab shared between the two characters. As I understand it, I would need to have two separate versions of the same tab on both characters, which means if I needed to edit it, I'd have to edit two pages instead of one. If it were possible to share a tab between characters, you'd be able to edit the same tab for both and allow a link between the two characters directly through the tab.
+1 I was just thinking of this and checked to see if it was possible. Would be extremely convenient!
