lately I've been noticing that almost none of my lens users realize there are more options available at a tap of the screen despite using the "Tap!" hint. Moreover, I try to include the "show reel" of some options upon lens initialization as seen with the official lenses.
This thread discusses the issue to certain extent.
My question is, what is a good practice that lets users realize there's more at a tap of the screen? Is there a smooth way, or shall I hack it? :)
