What does the implementation look like ? Did you update the placement strategy I had done for the backend placement ?
Maybe the tabs management could be merged with the placement editor.
Initially we had thought that tabs could be defined by the shapes themselves in the placement.info, so there is a default, and users can change it. Is it compatible with this technique ? It all relies on how you render those tabs actually. I think we had decided
in the meeting to use the zone name, with a specific syntax to define a tab. Something like Content[Security]:5 or
. I don't recall it exactly, maybe there is a bug open with the details, but I think it should be the solution.
Maybe the tabs list is hard to handle because they can be defined by the placement files, and also by the user. Maybe you can just add/remove custom tabs, and display the merged list in the placement editor.
