Use emojis instead of the folder icon in the bookmarks toolbar

[RShep33]

I use my bookmarks toolbar as a quick access for a lot of my links - on the left, i have the websites i browse every day, and then i have a bunch of folders in which i have all the other websites, organized by category (news, social networks, etc.).
While it's possible to give whatever name to the folders (including emojis), I wondered if it was possible to replace the folder icon by a customizable emoji - this would allow to put the newspaper emoji for the news folder, for example. It would also allow to only have an emoji (and no text nor folder icon) in order to gain space on the bookmarks toolbar.
I'm joining a picture of my current setup (on top), and what a setup with emoji replacing the folder icons would look like.

Overall the bookmarks feature has been left alone for quite some time. There are a few features that have been recommended that would really enhance and modernize it.

I think emoji icons for folder icons is a step in the right direction as its widely supported format. This could even be furthered by allowing customized icons. Possibly <svg> to be used.
