I often use filters in the search input by manually typing them, like with:images.
There are multiple filters, starting with different prefixes. in:, :with:, status: and so on.
It would be nice to have autocomplete suggestions when we write one of those in the search field.
Typing in: would show a selector containing created, posted, likes, bookmarks, unseen, watching, all, messages, pinned, first, wiki, title, tracking, see so we don’t have to memorize them all or look for them in the advanced search form.
Pretty much like the /filter feature, without having to preselect the filter from a prefix list.
