Some windows are not in the window list

[louies0623]

Some windows are not in the window list and cannot be restored after shrinking.

[probonopd]

This is partly intentional: Only application windows should be in that menu, not dialog boxes.

[louies0623]

This is very inconvenient, and it will be very inconvenient to use it under multiple applications. "Where is the window I just reduced, and why the menu does not appear?" This is a problem that often occurs when I use it.

[probonopd]

The solution would be to set the window type of Wizard/Assistant type applications (like the ones you are showing) to something that gets recognized as a standalone application rather than a dialog box. This needs to be done in those applications, not in Menu.

It’s better to have a Dock. If you have time, you can disassemble the Dock operation method of this video.

There is still the Dock.app for those who need it.

@probonopd Please open this issue: Xfe is not on the list

[probonopd]

These are the X properties of the Xfe window:

Does anyone have a clue as to why this code does apparently not get this window?

Telegram's appimage is not on the list.

[probonopd]

Please run the xprop command, click on the Telegram window, and post the output here. Thanks!

I don't see why my code should filter out this window. Maybe someone else knows?
