Nice and simple, but Masonry implementation is lacking

First, this was very simple to install and start using. No editing templates, no messing with shortcode. I was able to add a gallery to a post as easily as with the built-in gallery block.

However, the way that masonry (image stacking) is implemented leaves a lot to be desired. It only gives you a 3-column layout, which isn’t responsive-friendly. The columns scale to fit the window, so you wind up with massive thumbnails if you have your browser set more than 1000px wide.

Instead, I should be able to set the maximum width of each column, and the masonry layout should be able to add and subtract columns as needed.
