I'm helping a friend revamp a voting application.
During vote creation we would like to let the user remove a proposition by sliding it to the left (rows 3 to 5 in the preview below).Update
I might have be more precise about the fact it's a mobile app without authentication, which mean we keep no track of user. So, if a user revisit we don't want to block him with a tutorial he already saw (which is something that become annoying after a few times)
How would you hint that interaction?
