Search is completely useless, it never-ever finds anything. Threads are supported, but their functionality is not configurable so whenever I lazily click on the complete thread (instead of opening it, scrolling down to the last item and clicking on it directly) it opens every message of the thread. Really nice functionality for large threads with 60+ emails!

So I am a bit skeptical why on earth they would increase their coverage when the already supported platforms lack decent UX.

Maybe there's a demand for a more feature-rich mail client on iOS, perhaps syncing accounts and filters from the desktop app. But this doesn't seem to be that, at least not at this point.

(The bug is they do 'clever matching', so wedding matches weds, and too many emails you weds for wednesday, you can't say 'just show the word I ask you for')
