Configure certain apps to only play effect when opening first or closing last window

[JosiahFu]

The Idea

For some applications I would like it to only play the animation when the first window opens or the last window closes. For example, when I use firefox, splitting and merging tabs causes the animation to play, and I would prefer if it only was used when I first boot up firefox or close the last window.

Ideally you'd be able to set this per profile in the profile constraints menu as a toggle perhaps.

The Alternatives

I could not think of any.

Hi there! Yeah, I think this could be possible to implement. Not exactly easy, because the extension would need to loop through all existing windows which is currently not required, but it should be possible.

I think it could be added to the profile option as a switch in the Advanced Profile Options: "Use this profile only if it matches exactly one of your windows".
