Right now it requires 3 clicks to switch between the vaults in the iOS app (click on the vaults icon, select the vault, click “Enter vault”). It would be amazing to have a way to switch between vaults in one-click. It might not sound like much, but a more seamless experience of working on multiple vaults would make a big difference.
Maybe above the vaults icon (in the bottom-left corner of the screen) there could be icons that allow you to switch to different vaults in one tap. Basically like Discord allows you to switch between servers.
