Hey, i have been using your image with this request merged and it works great, so thanks very much! Only thing missing for me is a feedback that the updates have started after you click the button, maybe a bottom right notification like the one for a finished update? What would also be cool is somthing like a "loading bar" that tells me the progress of the updates so you don't have to click through all to see if the updates are finished and you can reboot. But thats totally optional and not really needed for it to work well!

The updates start right when you click it. It doesn't go one by one 🙈

so clicking the update all button is literally like clicking all of the update buttons at the same time (that is the logic that happens underneth)

the only difference with the notification is that i added the scack name to the update completed one...

yeah i know but the user doesn't have any feedback that the button even works until the first update is finished and you get that notification, thats what confused me a bit at first, so a notification "Updates started" or something like that would help in my opinion :)
