MioMio is a free blogging and portfolio WordPress theme developed by Manoolia Digital Agency. The design style is flat and the overall color of the theme is purple. It comes packed with a theme options panel you can use to customize the theme.
The theme has features like Google Web Fonts integration, a slider with featured posts , widgetized sidebar and lots of shortcodes.
The theme also includes a portfolio section, where you can show-off your design skills. From this point of view the theme is pretty unique, because most themes with both blog and portfolio functions focus primarily on the portfolio section. This focuses on the blogging aspect, with the portfolio section as an add-on.
MioMio is fully responsive and what I liked the most at this theme is that it seems to be very well optimized for speed.
