MacOs - CMD + w support


I am using bitwarden since a view weeks and really impressed about the huge number of features have already have integrated (with really one developer only?!).
But there is one thing I am missing on MacOs. I have enabled the tray icon, but when I try to close the application (cmd + w) it closes completely. In fact it looks like there is no difference between closing (cmd +w) and killing the application (cmd + q).
