Hi Richard,
Thanks for that observation. It’s expected that users may have to tweak the css to ‘fit’ their use and their theme. Nonetheless, I probably shouldn’t use content if I can avoid it, since it is too common. I’ll put that one on the upgrade list.
Responsive display for sliders has been requested and discussed. I forget if it was via private e-mail or on the WP plugin forums. I’m sure it can be done, but it would be quite a challenge. Some things just require some screen real estate to look good and function. So it’s a question of time-invested versus reward. Other forum members are welcome to chime in. I will have another look for the next release.
