[Feature Request] Bookmark text only for folders

[khaosdoctor]

I think it would be an awesome feature to have the option to display only text for the folders in the bookmark bar:

like this:

@bradleyrichter Do you think this should be a setting, or should folder titles be shown all the time?

[bradleyrichter]

@liunkae I think it makes sense to show folder names all the time since they are almost unusable without names as shown by @khaosdoctor ...

[cndouglas]

Great, I'll take this. 😉

Additionally some page bookmarks just have a generic file favicon, or there may be bookmarks that have the same favicon (e.g. Github bookmarks) so it would be good to add text for a favicon as an option (but without by default).
