It happens all the time... Microsoft borrows an idea from Mac or Linux and occasionally Mac or Linux borrows an idea from Microsoft.
The Gnome window manager has a feature called places. It is pretty synonymous with the my computer concept in windows and is pretty handy once you start using it. However I expected to right click and add a location to the places menu but that doesn't work. Instead you open the nautilus file manager, navigate to a place you want to add. Click bookmarks, add bookmark. Now you have a new place. To me that wasn't intuitive at all. Who knew a nautilus bookmark was equivalent to a gnome place? I had to google for that info. It is also pretty plain looking. For example the folder name is not capitalized and the icon is your default folder icon. If that folder happens to be a mounted drive then it would be nice to have a drive icon instead. You can fix the capitalization problem by going back to bookmarks and clicking edit bookmarks, There you can give it a name different to the actual folder name. That still doesn't fix the icon problem.
The file where all of these bookmarks or "places" are being stored is in your home folder and it is called .gtk-bookmarks. The file will look something like this.
file:///home/afleak/Documents
file:///home/afleak/Music
file:///home/afleak/Pictures
file:///home/afleak/Videos
file:///mnt/haven Haven
The location Haven is what I added to the places menu.
Now if we could just change that icon...
