If you hide the server switch sidebar, on the settings page, there's no obvious way to get back to seeing your single Zulip server's UI. It turns out you can do it with ctrl-1, but that's really not obvious.
Some ideas for fixing:
Doing something here is a priority, since this is basically the first thing that anyone is going to try to do after toggling the setting to hide the sidebar.
Click server name to show webview. Done in #262.
Will add servers to the view menu in the next step. Like this:

@geeeeeeeeek in Window menu :)

@akashnimare The sub menu is done. But seems that window submenu is only displayed on macOS. Do we need to do the same on Linux and Windows?
Yeah, we should add the window menu on Linux and Windows as well.
On windows -

Looks great!
