[Feature Request] The option to pull up categories to fill vertical gaps

[Brancliff]

Not sure how to best describe this one in words, so here's a visual expression with a 'before' on the left and an 'after' on the right

If you have one category with a lot more bookmarks than the other, it can create a lot of empty space to scroll through. This space could be filled up by lifting categories that are further down the page and placing them in that empty space.

I agree that this would be nice, but layouts like that can be rather resource-intensive when done in Javascript and there's no standard way to do it in CSS either.

Fortunately, recent versions of Firefox have an experimental solution that is available by setting layout.css.grid-template-masonry-value.enabled to true in about:config. Then add the following to Flame's custom CSS:

[class^=BookmarkGrid_BookmarkGrid__] {
  grid-template-rows: masonry;
}
