Installed the beta 7 and start trying things. Moving my vault, enabling browser extension and mini application without any problem.
Menus language in spanish ok.
Vaults "Always open to" not translated to spanish
Browsers - Text don't fit well, see screnshoot. Extension Helper part not translated.
Updates - Text don't fit well.
So far so good, feels comfortable to use.
