Change a window's opacity from the title bar right-click menu.

Opacity Slider

Right-click on any window's title bar to tweak its opacity! Works great in conjuction with the existing 'Always on top' option.

This even works on some windows that don't have a title bar, such as Firefox's Picture-In-Picture videos.

Changing window opacity without this extension

Cinnamon also has a built-in way to change window opacity. You can enable it in System Settings -> Windows -> Titlebar. Under Actions, set Action on title bar with mouse scroll = Adjust opacity. Then you can adjust opacity with the scroll wheel while hovering over the title bar.

This however can be less convenient and much less precise, and it doesn't work for Picture-In-Picture. Opacity Slider works with or without this option enabled.

Nice! Exactly what I needed. Planning on keeping the opacity state of windows permanent any time soon?

What do you mean by permanent? Across reboots? That's a much bigger task than it might sound like, but I'll consider it.

I'd also like this feature.

Actually, it isn't something I really need. I've found another way to adjust opacity of the elements I wish to make permanently translucent, and I don't need to adjust them frequently. Nevertheless, I like this extension for what it does.
