layout related tabs

Now a lauyout has multiple tabs for each part.

for example I take the template number 5 (that has 3 part):
In this template I can set a program into the part one (called a), two program into the part two (called b and b1),
and three program into the part three(called c,c1,c2).

In add I can set a relation between (for example) the program “a” and the program “b”, and between “a” and “b1”.

The very good thing is that I can set the father of a program (at now, I think, just to understand what relation can be suggested).

Suppose to have this scenario:

  • b and b1 are sons of a
  • c and c1 are sons of b
  • c2 is son of b1

The feature request I ask for, is that when I click on the tab “b1” only the “c2” has to be shown, and when I click on the tab “b” only “c” and “c1” have to be shown.

Thanks
