Different Icons that use the Segoe MDL2 Assets font for displaying the titlebar icons.

Changes that I made

• Remove selection from window buttons
• Use default cursor instead of hand (like other windows)
• changed opacity to 80% (like other windows)

.window-buttons {
	user-select: none;
	-moz-user-select: none;
	-khtml-user-select: none;
	-webkit-user-select: none;
	-o-user-select: none;
   font-family: "Segoe MDL2 Assets";
   cursor: default;
   opacity: 0.8
}

• Changed close button hover colors
• Decreased font size
• Removed boldness

#close-button:hover{
    background: #E81123;
    color: white;
}

.notion-light-theme .window-buttons {
    [...]
    font-size: 12px;
    [...]
}

• Changed glyphs for buttons

Glyphs

• Changed glyphs for maximize / restore

browserWindow.on('maximize', () => {
	maximizeButton.innerHTML = "ण";
})
browserWindow.on('unmaximize', () => {
	maximizeButton.innerHTML = "&#xE922";
})

Disclaimer

• No dark mode support (yet)
• Not thoroughly tested

I changed the variable of the button to maximizeButton (from element), so that this method would not change the wrong button. (Don't forget to init)

Requirements

You (maybe) need to install this font, but it should already be installed in Windows 10 by default

segmdl2.ttf

This font contains all the default windows icons
