Wayland Development Status
What’s been done recently, what people are up to currently, and
what’s still on the horizon. Look at wishlists from GNOME and
KDE, along with upstream plans and desires, and frequently
requested features from the larger community.

Discussion Notes from Wayland Cross-Desktop meeting
Tray Icon / Notification
▶ Use fdo notifcation spec version 1.2 or later
▶ Media player “remote” controls, already solved by mpris spec
▶ Use use-case specific xdg API’s, where available
▶ Clearly document that a tray-icon may not work everywhere
Global hotkey bindings
▶ Configured by the compositor
▶ Apps expose “actions” for the compositor to bind keys,
gestures, voice commands, etc. to
Colorpicker API
Add actions to “minimized icon” context menu

Discussion Notes from Wayland Cross-Desktop meeting
Screenshot / screencasting API
▶ Security check left to compositor
▶ Need xdg API for passing back a 32-bit RGBA buffer handle
▶ Screencasting needs an xdg API, incl format negotiation.
Dynamic Icons
▶ Apps can make runtime change to icon?
▶ Extend notification spec to allow apps to display badges next
to icon?
“Active” keygrab for virtual-machine viewers/games
▶ Reserve one key combo for compositor to break grab
▶ This might tie into Pointer Lock
