Sure:
I did this by sight. It looks OK, though it’s still not great.
// Improve Messages sidebar padding
.messages-nav.nav-stacked a {
padding: .4rem;
}
.messages-nav > li:not(.archive):not(.noGlyph) {
margin-top: .9rem;
}
I would like the following feature as well, though:
Use the full names of groups instead of their usernames. (This is a preference, but it would be logical to follow the dictates of the “name over username” setting.)
In general, group’s full names are not used consistently throughout the app. I just tested it and there’s also an issue when adding a user to a message. I can search for regular users by their full name, but for groups I have to mention them by their (occasionally cryptic, in our case) usernames.
