First, thanks for this awesome plugin, it's super helpful in certain situations!
I wanted to offer a couple suggestions. 1) either set the cursor to cursor:help when hovering over a tippy link, or give us an easy option to do so. 2) Create a box in the settings that allows us to input custom CSS for the plugin that won't be overridden when updating the plugin (this would also solve #1). So we can set things like font, color, etc right in the plugin settings, and it would be preserved with each update (assuming the CSS was the same in the update--but even then we'd still know how we wanted it, just have to find the new class/id/etc.)
Just some ideas. Thanks again for the awesome plugin, whether you implement the suggestions or not.
