Items 1 and 3 (re double tapping) are key issues for me trying to get accustomed to. Countless times now I have inadvertently removed research items from the queue because as I read the description of what it does, it says to double tap to add to queue, however once you are at the point where you can read the description, you've technically already tapped once, apparently.

Anyway, since this thread topic mentions tutorial videos - and there have been lots of other comments for people requesting a written manual - I'm wondering if removing the video tutorials altogether (and replacing with a manual with screen shots) wouldn't bring the file size of this game down about 200mb or so? I know I wouldn't mind... Just a thought.
