popup_during_fullscreen: Expand to allow all new floating windows.

[orestisfl]

Welcome

• Yes, I've searched similar issues and discussions on GitHub and didn't find any.

Impact

• This feature requires new configuration and/or commands

Current Behavior

popup_during_fullscreen depends on the WM_TRANSIENT_FOR property both for smart and leave_fullscreen.

Desired Behavior

Extend popup_during_fullscreen to allow all floating-by-default windows since those are often notifications, popups or helper windows that the user doesn't want to miss. These for various reasons might not have the WM_TRANSIENT_FOR property. For example, if an application different than the focused one is showing the popup or the focused application might not set the hints because it might not be complying with that part of the standard or it might be using some external tool like zenity to show dialogs.

Please note that new features which require additional configuration will usually not be considered. We are happy with the feature set of i3 and want to focus in fixing bugs instead. We do accept feature requests, however, and will evaluate whether the added benefit (clearly) outweighs the complexity it adds to i3.

Keep in mind that i3 provides a powerful way to interact with it through its IPC interface: https://i3wm.org/docs/ipc.html.

Will this be an opt-in change, or are you suggesting to change the existing behavior without a way to opt-out? I’m a bit worried that people will realize they are dependent on the current behavior for some use-case.

Yes, I am suggesting it as a new option, e.g. popup_during_fullscreen all

Sounds good
