It is hard to organize the saved browser bookmarks over time and simply alphabetical sorting is not too helpful. Having a “sort by URL” feature in browser bookmarks can help group the URLs (Webpages) of common interests together, thus saving time and being productive in organizing.
I understand your suggestion and am not taking away from it. I very much agree it would be nice if they could add extra options to how we can sort things. My comment here is just to offer a suggestion for a way to work around this in the interim.
Don’t forget you can provide custom names to each bookmark and even create folders. So you can list things like Brave FAQ, Brave Community, etc and then it would group all of your Brave webpages much as the way you are expressing. Each time you save a bookmark, you would just make sure to name it.
