No, and I don't have the impression that we can get that information any other way from a zwlr_foreign_toplevel_handle_v1, but I could be wrong (I'm not sure I see how this works in the background yet, I'd probably have to get into a compositor's code for that).

More generally, I feel like only the KDE protocols really provide the properties we're used to on X11. In this case plasma-window-management provides this information, among many others. Not to mention virtual desktops, which only plasma-virtual-desktops seems to offer.

The problem is that apart from Kwin, no other well-known compositor seems to implement these protocols. So we'll have to deal with these limitations, which means that some panel features and plugins will have to be (at least temporarily) abandoned.

Or we have to start writing a compositor that implements all this, but that seems to be a huge task, for a questionable gain. Personally, I'd much rather contribute to something that already exists.

Cheers,
Gaël

For the second one, which covers at least part of the Libwnck features, a small library could be written, if necessary (I haven't tried to tinker with it yet).
