Once opened, mounted partitons use the same launcher icon as the home folder.

I was wondering if this behaviour is a bug or if it's meant to be this way:
I'm on Ubuntu 13.10. On my launcher I have an icon for my data partition and the default icon for my home folder. When I click on the partition icon, a nautilus window is opened showing the content of that partition (let's call this window A). The problem is that window A "uses" the home icon insted of the partition icon (i.e. the home icon is highlighted), so after you minimize window A you'd have to click on the home icon to bring it up again, but of course this opens your home folder instead. Clicking on the partition icon does nothing, not even open a new partition window.
The only way to bring window A up again is using the scrollwheel, which is normally used to switch between different windows of the same application.
I think that windows for partitions should use their own icons, so it would be easier to manage them and understand wether you have your home folder or your partition opened.
Should I report this as a bug?
