>1 row of tabs.

If you have two or more rows of tabs on the top of a tabpanel Servoy always moves the selected row to the bottom. It is a cool visual effect but I would love to be able to turn it off. I find it harder to find the desired tab when it moves from one row to another.

It is behaviour of the UI libs provided in Java (using the system libs in some cases) we cannot alter that.
Since Servoy 2.1 b6 it is possible to enable tab scrolling (via property on tabpanel)
