Hi,
I think one of the most important focus should be
– the hover function. In some items (such as icons or blogs images) hovering is sometimes unuseful or annoying, enable turning off hover function could be very useful;
– make blogs images size editable (the huge article image is a nightmare);
– social sharing shortcode: enable the choice of social included and social excluded, as in header options;
– some new buttons design. Buttons are the feeds of a page, and some more design options could be appreciated. Something like the one attached
I made all of those things using CSS but including some options in theme could be smarter.
