1) How do I use the same layout (created by Layout editor) to create multiple tabs?
* I tried tabctrl.Add(tab) but it only shows the contents 1 time, then I get empty tabs.

Each widget can be added only once. Second call of Add() removes Ctrl from its previous parent before adding to a new one. This applies to all Ctrls, not only tabs. If you want to have the same thing in two locations, you have to create two instances of it. E.g.:

WithMyLayout<ParentCtrl> tab1;
WithMyLayout<ParentCtrl> tab1;

tabctrl.Add(tab1);
tabctrl.Add(tab2);

Thanks!
I got the behaviour I wanted with:

// init code
int tabcount = 0;
WithMyTabLayout<ParentCtrl> tab[5]; // here I set how many I want

// code to add:
tabctrl.Add(tab[tabcount], "Tab " + AsString(tabcount));
++tabcount;

//code to remove:
tabctrl.Remove(tab[tabcount]);
--tabcount;

Besides that I just add ifs to check if 0 >= tabcount < 5, so I don't go out of the array boundaries.
