Set one layout permanently

[azizsayfiddin]

I mostly just need scroller and don't really use other layouts. How could I possibly just set scroller?
I tried to have only scroller in circle_layout but it didn't help.

circle_layout=scroller
tagrule = id:1, layout_name:scroller
tagrule = id:2, layout_name:scroller
...
?
