The circle genlist is great for selecting from a list of items like for example contacts. If the list is huge though navigation gets a little cumbersome. There is a feature called fast rotary action to solve this problem. But according to the linked documentation it's not available in a Tizen native API app.
What is the best way to implement quick navigation in a huge circle genlist in a Tizen native API app? Do I have to come up with something myself like an upstream A-Z list to link into the circle genlist or is there some recommended way of doing it?
