Thank you again for your great work — even after years it is still such a pleasure to work with LayTheme.
For the last iteration of my website (https://franzgruenewald.com), I use LayTheme in a way it is certainly not really designed for. Every project has the same structure, including a small description and a Element Grid with Lightbox enabled. For categories, I also use the same layout of a Project Thumbnail Grid throughout the site.
Now, if I would like to quickly change the layout type / row gutter / column gutter / thumbnails per row of all these grids, I would have to manually go through every category and every project, right?
For that reason it would be super nice to have Element Grid and Thumbnail Grid defaults with a "Apply Defaults to existing Grids" functionality, exactly like you did with the Gridder Defaults.
