With the next version of rgsmoothgallery another design is available for you! Thanks a lot to Sandro for the work and to let me use it!
The original files are included, so you can always modify it to fit better to your needs.
The following configuration is used for the demo below:
Finally you also need to include the new css file with this TS Code
plugin.tx_rgsmoothgallery_pi1.pathToJdgalleryCSS = EXT:rgsmoothgallery/res/css/jd.galleryCool.css
If you created a new design, please let me know!
