I've created a Github ticket for adding the systray functionality to the
core. Since the actual systray in Windows 11 doesn't support first
letter navigation, nor does it support home or end to move to the
beginning or end of the list, it can no longer be argued that the real
system tray is better when it is actually less functional and efficient.
You may read and comment on the ticket here:

And that includes supporting the proposal. If it gets no support, it
will be less likely to be implemented.
