At this moment there is a big limitation on how you can build a screen.
Each new detail is a rectangular box with a new layout. One thing I would like to be able to do is this;
---------- ---------------------------------
A
---------- C
B
----------- ---------------------------------
With a relationship A → B → C
With the current screen engine this is not possible, and it will become;
----------
A
---------- ---------------------------------
B C
----------- ---------------------------------
It would become possible to create different screen layouts, and give much more freedom if a detail area could be linked to another detail area, instead of the main subject, within one screen.
I understand that implementing this would be a huge change, but it would give much more freedom.
