So, with all respect, what is the advantage of multi-vaults over multi top-level directories in one vault?
I can only see the possibility to close one or more of the vaults in order to reduce the number of notes “active” at any time? For reduction of “clutter” in the explorer menu? But what then happens to inter-vault links?
For me, I am very happy to see multiple vaults, but I use them so that I can separate aspects of my life which have no serious intersection, or where there is confusion of vocabulary that might result in false links (for example, as you can see from my avatar I do horse related things. I am also a software engineer. “Bits” have very different meanings in these two parts of my life and I will surely use two separate vaults to keep them apart).
What is the essence of the need for multi-vaults, within one UI context, and each cognisant of the others contents? I imagine I am missing some key idea here?
