### Summary

Scroll down/up automatically while moving a vault to the bottom/top in the vault list

### Motivation

As a user I want to be able to move the selected vault to the bottom/top of the vault list regardless of how long this list is.

### Considered Alternatives

Currently, you can only drag it into the visible size of the window as window does not scroll down/up automatically. You have to drop it and then physically scroll down/up and then drag the vault down/up to the bottom/top of the window and repeat until it is moved to the bottom/top.
