Looking at the second screenshot, Event should be Events as the rest of the section headings are pluralised (excluding Comcode page which should also be pluralised).

"Staff actions" is used as a general term throughout the CMS. For a site that's opened up it won't quite apply, but it's hard to clearly delineate terminology so I'm happy enough with the decision to use that term. People can change the STAFF_ACTIONS language string if they like.
However, I do think the dashboard would better say "Action log", so I'll make that change.

Not showing the title is an issue specifically for catalogue entries. We'd either have to code the unvalidated module to understand catalogue entry structure, or ideally implement #2249.

"Event should be Events" - fixed.

Happy with the string, my confusion was whether it was actions of staff, or actions for staff to see.

Comcode page should be Comcode pages too :)
