the tray icon thingy is not in the plan, at least for now. I haven’t personally studied how to implement it, but as @joekamprad has said elsewhere, it involves lots of extra work, and unfortunately I don’t have that time currently.
But if anyone can help and come up with a (preferably small and simple) bash script for creating a tray icon notification, I can take a look at it (but no promises though).
But there are some workarounds you might want to do.
First of all, you could disable the related systemd service:
systemctl --user disable eos-update-notifier.timer
and reboot. Then it does not notify about updates anymore, but you’ll get all other features by manually running terminal command
anytime you want to update your system.
And you could even create a launcher on your desktop for it by right clicking the desktop and selecting Create Launcher (or similar, I translated this on my desktop…). The command for the launcher is “eos-update-notifier”.
