so i have to remember mount points or symbolic names by my self.

i use latest stable version
Version : 0.13.1

Mount points might be an improvement, but the problem is that not all volumes are mounted. You could use a volume as a raw device (some databases do this).
I think in this specific scenario, using the VG+LV name as the device name would be better. But since it's all just tags, why not both? :-)

I want to mountpoint as label also, not only VG/LV names.
