Button margins

[ghost]

Hi! Sorry for another issue but it seems like one of the button styles fixes was imported from an older commit (probably one of the previous --amend's)

currently the styling looks like this:

button:not(:first-child) {
    margin-left: .5rem;
}

though this causes problems with the alignment of the "users online" button in the chat (by adding a .5rem margin to the left)

changing the styling to this will fix the problem:

button:not(:last-child) {
    margin-right: .5rem;
}

This change adds horizontal scrolling to settings panel (reverted to your version because of too many stuff to hide manually).

Got it! Thank you!
