Now that Enpass 6 supports multiple Vaults, I was moving my work-related items to a second vault, and school items to a third vault. I find it would be useful to support OneDrive for Business to sync in this kind of situation (my school uses Office 365 Education, which I think also uses OneDrive for Business).
OneDrive for Business also supports the "apps" folder, where you should save Enpass data.
