If I go to Manage Sites, I can see the numbers of updates for each category column (core, themes, plugins). If I click on one of those numbers, for example, plugins, to see the list of plugins that need to be updated, it is not possible to go back and continue updating that site. I have to go back to Manage Sites, find the site, click the next category, and then start the process again.
If I click the site title in Manage Sites, I can see the overview for each category, but I still have to look at details to see all the detailed updates (for example, I am not going to click “update all” without knowing what will be upated). It would be very useful to be able to see a list of the updates right on the overview page, to prevent having to click and go back so often, especially since it’s not possible to go back to the site overview page.
