Feature Request: Show Drive Capacity Bar Under Devices in Left Bar
One very useful feature I have seen in many other file managers is some kind of indicator for how full a drive is under the left-hand listing. Typically in Linux file managers (nautilus, for example), there will be a single pixel (or 2x px on larger screens) bar with a white background and the theme's fill color to show how full that drive is. It is very simple, not overwhelming for your average user, but is useful for at-a-glance drive management.
