There is an issue with loading the css code, once I turn on css minify option. Left top corner "No theme CSS loaded" appears.
In galleria documentation I see you could load a theme manually using <script>. Also "You can put this script anywhere in your document, before initializing Galleria. To speed things up and gain more control, you can also load the CSS file associated with the theme"
Looking at the galleria-fs-theme.js there is only one default theme, so it would make sense to load it manually unless there is going to be other themes added later on.
I know this is rather big request, but it would be great as W3TC plugin is a must, as speed is very important on site ranking and general user experience. In my case with 10 plugins running it will speed up my website by roughly 15%-20% which is huge.
Let me know what can be done.
