The icon doesn't match the Breeze theme

[NerosTie]

I think the default icon is too "Arch" and it should more like this one for example:

Well, Arch is definitely the target distro here, it's even included in project name. The above icon is already used by Discover so reusing it isn't advisable. If other Arch-like distros want to package this, they can use icon of their choice.

Yes but the actual icon doesn't look like an update icon and it's doesn't match well with the Breeze theme. I don't tell to use the Discover's icon, but something more like this one for this plasmoid.

This is probably very subjective as it looks good in Breeze for me but I don't oppose adding new icons.

It's an arch icon because only arch requires check updates and manual upgrade.

Gnome arch update notifier uses a similar arch logo icon
