I am using Nemo instead of Nautilus as my primary Ubuntu Unity file manager. When I right-click the icon on the launcher bar it shows the folder name of open windows, as shown in this screenshot here. I'd really like it to show the full path, however, as frequently I have multiple windows open with the same name and can never find the one I'm looking for.
If you tell me to left click twice on the icon to make it show them shrunk and spread across the screen I'll say I find this feature to be almost useless. Sometimes I have 10 or more windows open when working on big projects and trying to choose the right one that way is worse than using Alt + Tab, which is also very slow and tedious.
A simple right-click on the launcher, showing enough folder information (ie: full path) that I can identify the open windows is just what I need.
