Hi Jeff,
As for responsiveness, it is driven more by the THEME than by the PLUGIN. The MSTW plugins are developed and tested on the WordPress Twenty Eleven theme, which is fairly responsive, as you can see by playing with the window sizes on my plugin development site. I try to avoid anything in the plugin design that would ‘break’ whatever the theme does. That said, there are some places where I did not think it made sense to do so. For example, the Game Schedules slider is fairly unresponsive because I wanted to keep it looking good and looking like a slider. I guess I could allow it to shrink down to only one game displayed on the slider, but then it’s not really much of a slider IMO. At the end of the day there’s a trade in making things “better”, like more responsive, and leaving them “good enough”. I regularly battle ‘computer geek’ gremlins that try to convince me to do something that is “cool” but take a lot of work and maybe 2 users would ever notice.
ANYWAY, if you want to call out specific areas where you’d like to see more responsiveness, let me know and I’ll add them to the list and work with you to see if the plugins can integrate better with your theme wrt responsiveness.
