The idea is good, unfortunately it is made more intuitive view completely illogical. It considers it unfortunately the other way around, as intended by the developers. Each I gave it up, held it differently. Had the tape covered on both sides with a measure, it would be no problem. So it is around now and can not be used basically.
In addition, I find it very unfortunate that it does not pick up. I think this feature is useful as an automatic extension.
