Daily UI Challenge: Ch. N5, N7 and N22

Daily UI Challenge: Ch. N5 (App icon), N7 (Settings screen) and even N22 (Search).
Ended up with a pleasant and different settings icon. Made the corners of the screens more round for the presentation. Added the bottom navigation bar for easier access to the most important actions. Icons big enough and with enough space so that "big fingers" don't press smth by mistake.
