And the mystery deepens or rather reveals something?
@m_shebin just replied to our tweet about “File manager request marked complete” and it seems “Store apps & attachments on external storage and improve/provide micro SD support” feature request is also deemed complete?
So, it doesn’t look that odd now and may be it is indication of either GDR3 (not mentioned officially though) or WP8.1(Too late) bringing these two features. Or, hopefully MS may have planned smaller updates or standalone apps for bringing these features to OS.
Don’t want to think negative for now and let’s wait for some official communication.
