"Update all"-button should show some indication that it has been pressed

**Is your feature request related to a problem? Please describe.**
In the updates section the bottom right button "Update all" or any other UI-element doesn't change in any way, shape or form when the button is pressed.

**Describe the solution you'd like**
The "Update all"-button should show some indication that it has been pressed or/and the UI of the page should change in some way. The installer notifications are not enough as somebody who doesn't have pop up notifications enabled.

Thanks for all the work put into this project.
