I would like to alter the spacing of the input fields and minimise the amount of linked files in my <head>. Obviously changing the css in the plugin directory will get overwritten upon update and I can easily override styles in my main css file.
What this leads to is a suggestion for a feature to turn off the plugin linked css so that it doesn't add a link in the <head>. Then one could copy all the required styles to the theme's main css to customise. I think more advanced users, including myself, would appreciate this.
