It's a good idea and I wish I could use it to reduce clutter, but it's just not a very good extension. You can't middle-click items, you can't add fav icons if you want them, folders are always open (I'd rather they be collapsed by default). It's an OK extension if you just have a handful of bookmarks toolbar icons, but I primarily have folders filled with lots of items.. so my list is huge in this extension, and requires tons of scrolling. Not for me.
