Comment 67 for bug 48671

@J That's a great idea.

The side panel can actually be changed into an information side panel. If you click on places, the second option is information. The dedicated information field could also be combined with the preview area I talked about earlier. So editing the file name may be done by clicking into the information area for the selected item. You don't click into the information field for navigating through files, so chances of mistakenly editing the file names are next to zero. The layout of the name field suggests that it may be edited. You can differ about the details, but this is how it could be done, in my humble opinion.

Since the file-name is displayed anyhow in the bottom status-bar, this status bar could be changed to include an editable name-field like the one you proposed. It should be visually apparent that this area can actually be edited....
