Hi Support :) After last update SP Page Builder was added option to add in gallery addon description:

1. Thumbnail Description
2. Full Image Description

My thumbnails have 320x240px size and I want only Full Image Description, it's works but text of the bottom of image is truncated to thumbnail size :) sppb-gallery-desc class have max-width:320px

Can you change it in next update?

Now I add to custom.css: .sppb-gallery-desc { max-width: none !important; }
