This post was made with another stylesheet and it might be messed up!
Minimized windows in Gnome Shell can easily be forgotten, or go unnoticed as there is no indication panel present any more.
Thankfully, an extension that shows a semi-transparent list of currently minimized windows on the desktop (behind all other windows) was released recently acting as a reminder that the minimized windows are still present.
In order for the extension to work properly, you will have to enable the “File manager handle the desktop” option from the Advanced Settings menu (Gnome Tweak Tool).
To install the extension simply turn the switch to “ON”!
