Post Title should not be mandatory and character Limit is too less(60), it should be at least 160.
People love to post just photos, they cant want to waist time to think of Title, So make title not mandatory and add option for multiple images upload at a time, now if anyone want to upload 5 photos , then h/se have to tap camera icon 5 times which is boring.
Great suggestions, we added them all to our Wishlist :)
