IIRC, in previous Fusion versions, the All Programs apps list appeared also for Linux VMs (similarly to Windows VMs): so, has this intentionally been removed, as a feature, in Fusion 6.x?
And there's no appListCache folder inside the Ubuntu 14.04 VM bundle (as there instead is inside Windows VMs): so, probably the feature is deliberately not "active" for Linux VMs.
Any chance of bringing back this useful feature?
P.S.: BTW, Parallels Desktop 9 creates a Dock folder also for Linux VMs.
