Some volumes are not detected as offline.
OK, but that USB Stick was shown as "offline". And there never has been (If I remember it right at least) any of the offline indexes / hard drives that were shown greyed out respectively its files and folders (which I would prefer). Could one assign another colour for offline elements or another background or not boldand the online elements bold?
So one has to enter
default: offline_alpha=255
in the search field and press ENTER to get the offline elements displayed like the online one are shown?
