It is useful to view (perhaps with a label mobile) node connecting the various disk / partition because it may happen to have the same size and without a proper name. Reproducible: Always
Thanks for the report, but I'm afraid I'm not sure what exactly you mean. Could you try to describe your wish in more detail?
In the list of devices currently shows the name and capacity, but this may be insufficient. I therefore propose to display the node (sda1, etc..). Now looking back, I will open a new request also with different and more details. :)
Thanks for the feedback. This has been reported already. *** This bug has been marked as a duplicate of bug 307883 ***
