Been dabbling with whatsapp+ theming for quite some time, created what would probably be the first I consider something decent. Will release other colours soon, when I have time. I do UCCW too for myself, and have plans to move into miui and cm, so I consider whatsapp+ a start.
Anyway here it is - minimalist holo blue, kept it as black as possible, text colours mainly in grey or holo blue. I'll release a white version too, and also with other text colours.
