CSS issue

This looks a really promising plugin, and it’s obviously under very active development.

Unfortunately, your use of inline CSS (especially with the !important attribute) makes it exceptionally difficult to re-style so as to blend well with any theme.

Could you please take out the inline CSS and move it into an external stylesheet, preferably taking out the !important attributes at the same time?

I’m also not a fan of including a custom CSS page as part of the plugin’s settings; it’s an unnecessary additional stylesheet, which just adds to loading time.

I much prefer to add my CSS to my theme’s style.css file, because styling is always theme-specific. The irony is that, while you include inline CSS with the !important attribute, it makes it impossible for me to make the changes I want, even if I were prepared to use the plugin’s custom CSS page.
