Also add an open containing folder action
Hmm, as your screenshot indicates, the subtitle is not very useful because it usually gets elided:
Not a -1, but I wonder how useful this will be in practice.
However big +1 on adding an "Open containing folder" menu item. Maybe that should be in a separate patch so it can go in quickly and we can discuss the subtitle separately>
I did this for readability, I think we should keep this.
Your screenshot made me think, we might want to replace for instance "/var/run/100/kio..." but the user friendly name that dolphin would display in places when the path correspond to a mounted place or a place, i.e "Pictures" instead of "~/Pictures".
Like dolphin breadcrumbs does basically.
