Preventing accidental delete of movie from watchlist

Dear developer team,

In the android app, when I accidentally touch yellow tick on the upper-left side of, or the word "watchlisted" under the poster of the movie that had been added to my watchlist, the movie immediately is removed from my watchlist. Considering that my watchlist is very long, I can't find the movie easily when this happens. You have feature like undo, but still there could be one more effective feature like the alert function. Whenever I touch the places I mentioned above, app should ask men or alert me by pop-up or dialogue box whether I am sure to delete the movie from my watchlist.

Regards,

User
