There initially IS a mount button for the partition. But if you unmount it (expecting to be able to mount it again at some point in the future), you can't because the button is no longer there. The expected behaviour is inconsistent.
Hi,
If I mount a disk in UD, then unmount a partition, I lose the 'mount' button for the partition and can't remount it unless I unmount & remount the whole disk. Am I missing something?
