Summary

It is a small tip about Cinnamon desktop environment, which is well known as the standard of Linux Mint.

I have moved from Mate to Cinnamon recently.
(Well, I like Mate for its good balance between lightweight and usefulness.)

Cinnamon has a lot of useful function and elegant effect, and most of them satisfy me.
The default style of "alt + tab" windows switcher is one of few exceptions.

Before

Configuration

In the system settings window, go to [Preferences] - [Windows]:

Choose [Alt-Tab] tab and set up [Alt-Tab switcher style]:

The options are:

• Icons only
• Thumbnails only
• Icons and thumbnails
• Icons and window preview
• Windows preview (no icons)
• Coverflow (3D)
• Timeline (3D)

After

With bigger icons and also thumbnails:

It's better to me : )
