I mostly use the Recently active topics page (mostly the start page widget to be completely honest) when browsing through community posts.
Like other pages—Product news, Ask the community, etc—the Recently active topics page has a simple sorting function. It would be nice to have the same function in the start page widget as well.
But what would be even more nice is filter options in general, and a language filter in particular. Basically being able to filter posts based on language, to only show posts written in English for example.
