add cycle navigating through multiple collections
currently, if I have multiple collections: a, b, c, d, I can only navigator forward or backward. For example, I start with a, go to b, then, c, then d. Now if I want to go back to a, I have to go back 3 steps. The more collections you have, the worse this problem gets.
How about make it like a, b, c, d, a, b, c, d... ?
